    CushieAudio, customer service the way it should be
    Skot helped me find the right GROM audio product for my 2003 UZJ100 Toyota Landcruiser Sahara.

    I unplugged the 6CD stacker, plugged in the USB3 unit in its place, the bluetooth dongle and the handsfree microphone, turned on the ignition, paired the phone and immediately have quality audio. Immediate WAF, wife approval factor.

    Thank you Skot, I did not know I over-ordered but you immediately updated the order and refunded the difference. All the best.

    Hi Skot

    Just a big thanks for the usb3 unit for my Subaru Liberty Gen4

    Works well and exactly what I was hoping for

    There was a dealer fit ‘option’ but this seems to be no longer available. We found your website and the items specifically for a Subaru Liberty, and went from there

    Connection is great

    Sound quality is great

    My Dad thanks you for the assistance and advices and prompt replies

    And we used SSV in Mitcham 3134 for the install – clean and smooth. Thanks to them. Please add them to your list of recommendeds

    Such a nice unit and thank you

    The Grom USB 3 with the Grom bluetooth dongle works a charm for music playback with clear sound at both high and low volumes! The microphone is very low voltage and is a slight hissing on the other end of the call but is a minimal compromise for my car which didnt have bluetooth let alone hands free!! Overall great customer service and everything came as expected and fast! I have a 2005 Subaru Liberty with the micintosh sound system and it works a treat!

    When you type in “good customer service ” at Wikipedia it takes you to Skot’s pages at Cushie Audio. Even though the Grom products are sourced from USA Skot is very well known to them. I know this because I have checked out the Grom website. This involvement in his products really shows. Nothing is too hard for Skot to do to give you a good experience and a better outcome. This is my second time with Cushie and their focus on quality is consistently outstanding. My ears and the Alfa’s speakers say, “Thank you Skot “. Phil

    GROM3 USB for Subaru Outback MY07 and Forester MY07
    I spent a very long time looking at ways to improve the functionality of the factory head unit on my Subaru Outback (MY07 Premium Pack), the OEM unit is a Kenwood GX204KHF2. It’s an integrated unit that combines the aircon so a simple double DIN was not an easy option.

    After speaking with Skot I purchased a GROM3 USB with a BlueTooth dongle.

    Plug and play solution to add a BlueTooth hands free capability and music from my phone as well as a usb port. Stoked!

    So Stoked I purchased a second GROM3 USB (with BT) for a Subaru Forester X SatNav (MY07). The GROM works perfectly for the factory Kenwood GX804MF2.

    I’m now looking at purchasing a V-Line to improve the connectivity in our 2013 Toyota Prado.

    Very happy with the equipment and the fantastic service from Skot.

    The GROM USB3 has been a brilliant solution for my Subaru Liberty 2006, given the limitations of the McIntosh stereo. I have been able to easily adapt my older habits (CD player) with newer ones (Bluetooth) without losing the benefits (quality!) of the existing sound system. Michael from Bendas in Sydney provided top shelf convenient professional and personable service with his mobile installation service. Thanks also to Skot for clear and personable support.

    This product works well but has a couple of minor issues that stop me giving it a full 5 stars.
    – Maybe 5% of the time it isn’t recognised by the head unit (it emulates a CD changer in a Subaru Liberty) so I need to shut the car off and restart it.
    – I previously had an issue where despite being connected to Bluetooth no sound was coming through the speakers. The cushie team helped me resolve this.
    – The max volume is a little bit quiet, even with device volume on full
    – High volume on the head unit leads to minor electrical interference

    Otherwise it was easy to install and works pretty well. It took less than an hour all up to get working. Unlike an Aux cable you can use the next/previous track buttons to control your music which is great.

    Life made easy with Cushie!
    When I first looked at using the GROM product, I gave Skot a call to see if I was looking at the right product/s.
    Skot was so helpful and helped me to choose the GROM USB3 and Bluetooth Dongle (SUB08U3 + BTD) which was the best combination for my son’s 2008 Subaru Liberty.
    Skot also explained how it works and how simple it is to install. He pointed me to videos to show how easy it is.
    So once I convinced my son this was far more economical than the $000’s of dollars to give him Bluetooth audio and phone via a Head Unit, the purchase was done.
    So easy to purchase, quick delivery, and real easy to install.
    There was absolutely no need for electrical connectivity via soldering, crimping or alike, it was all plug’n’play.
    Skot has been more than helpful, and I fully recommend Skot and Cushie Audio.
    My strongest advice is to either chat to Skot via their website, or give him a call if you are unsure what you need to do.

    absolutely fantastic. so easy to install and connects to phone easy and sound s fantastic

    Really appreciate the support from Cushie. I had an old Grom (10 years +) which didn’t work probably and he assisted me in trying to get that to work probably. Once we decided it was past its useful life, he then recommended a solution and shipped to me ASAP.

    very satisfied with the new grom and the service

    Purchased a Grom USB3 for a 2004 Mazda RX8. Excellent product and superb service. Very easy to install. The hardest part is getting the side bolt out of the radio to take it out without losing it down the back. Everything worked perfectly first time. Awesome sound. Beats hands down putting in a new head unit and all the other harnesses for a Bose system so you can play a USB.

    Over 4 years ago I put a BT3 into my 2004 Subaru Outback 3R and it hasn’t missed a beat. I put a $1000 Pioneer head unit into my Volkswagen and the Grom actually works better. Also when driving the physical buttons of the factory radio (you can feel) are better than a touch screen that you have to look at. I recently bought a 2005 Subaru liberty 3R with the McIntosh stereo so added a USB3 and BT dongle. Works just like the BT3. When you find an older car in mint condition it’s great to be able to keep the factory setup and just add Bluetooth. Great service from Cushie too, give them a call if you are undecided, very helpful.

    I have a 2006 Liberty 3.0R spec b with McIntosh sound system and as everyone knows it’s a difficult system to upgrade . You pretty much have to change out the whole system , which would be pricey. After some research I decided that Grom would be a better option. Bought the Grom usb3 over the Grom bt3 after reading some reviews and on the recommendation of the cushie website. It’s a little more expensive but I think it was the right choice . I am very happy over all with the Grom . It was easy to install and the sound quality is good . However according to my son the sound quality is better using the USB over Bluetooth. He said that with Bluetooth there is a high pitch sound in the background but I couldn’t really notice. The hardest part of the install was taking apart the trim ( YouTube helped heaps ) and deciding where to locate the Grom. We decided to locate the Grom next to the driverside seat using some valcro to attach to the carpet . This provides easy access to plug iPhone to USB port of the Grom . I usually use the USB more than Bluetooth as I can charge my phone while listening to tunes. However Bluetooth can come in handy if you have passengers. Overall very happy with the Grom . I would recommend usb3 as it gives you the option of a direct connection to Grom and according to my son sounds better.

    Over the years, my 2001 BMW X5 has fooled me many times with aftermarket products that never work properly.
    The GROM USB3, however, does not disappoint. The installation was a breeze, seriously, and the sound quality is superb. All the functions such as steering wheel control and track display work exactly as advertised. No problems hooking up to my iPhone 11.
    The pre-purchase phone support from Cushie was excellent. If only other companies would take their customer service that seriously.

    installed on my Subaru Liberty spec b 07 – mcintosh stereo,

    plug and play, easy to install, works instantly and immediately. no issues with sound output,

    only issues i’ve had is the bluetooth is locked to the last phone it was connected to, you’ll need to disconnect the phones bluetooth to connect to another phone (e.g. when you want to switch between your playlist and someone else’s playlist), its not as simple as connecting to the GROM using the new phone.

    there was one instance when the GROM unit had no sound output, restarted the car, and it seems to have reset itself and worked again, otherwise very happy and works everytime.

    Lexus RX – super easy install. Took around 45 minutes, just taking my time and having a coffee at the same time.
    Spoke with Skot a couple of weeks ago and he advised me of the 2 options I had. I decided on the slightly more expensive option, as that provided more. Ordered from the link he sent me and item was posted without delay.
    I went with the USB with the bluetooth dongle. Glad I did as I am very happy. Easy music streaming and phone calls. Clear sound and good volume plus the added ability to control the phone via voice command. No need to touch the phone at all.
    Once the phone connection is established, that’s it. Auto reconnection next time the car is used. Even continues the music from where it left off.
    Overall, a Fantastic experience from ordering to install and use. Skot was friendly and helpful and I definitely recommend the products.

    I purchased the bluetooth unit with USB playback as well for 2004 Mazda 6.
    Its a great unit and does exactly what is described, best part is everyting integrates into existing controls like the steering wheel. Calls via bluetooth are clear, music quality is great, cant ask for anything more.

    Skot also provides great customer service.
    My headunit required some soldering but was ok with that even though i’ve never soldered before.
    After the soldering and hooking everything up the GROM unit wasnt being identified by the car when trying via USB, i called Skot and he provided support over the phone and through email.
    After pairing the unit with my phone and flashing some other firmware everything started working.

    I purchased the GROM USB3 along with the optional bluetooth dongle to add much needed music streaming capability to my 2007, Landcruiser 200.

    The Toyota navigation and entertainment head unit in the vehicle is actually pretty good, but just didn’t have the capability of playing music from an external device like my iPhone or iPod. Enter the GROM USB3 from Cushie Audio. It really is just plug-n-play. In fact, it was so easy, I thought I’d skipped a step. I think the hardest part was getting to the back of the head unit, although now I’ve done it once, I reckon I could do it in a quarter of the time (didn’t want to break anything).

    The GROM unit is, in a word, brilliant! I can plug in my iPhone via the usb and it is discovered right away and starts playing. The fact that it charges at the same time is an added bonus. And my daughter loves the Bluetooth dongle. She can connect to the system and play her music from the back seat, acting like a DJ to the rest of the captive audience! Of course, because all the steering wheel and touch screen controls still work as normal, when I’ve had enough of teenage music, I can turn it down, or even select a different track from her phone, or choose another phone (mine) for some music from my generation. The Bluetooth is so good in fact, it picked up my phone from upstairs while I was downstairs in the garage cleaning the vehicle, that was unexpected but nice!

    None of the Toyota factory options are lost either, as the unit just plugs into the unused CD stacker plug. The existing DVD stacker can still be used to play CD’s or even watch DVD movies and, by pressing the DISC button on the factory unit, the GROM appears as an additional CD stacker. It really is just too easy!

    While the Landcruiser has Bluethooth for ‘hands-free’ calling only, the GROM unit can also act as a hands free device and has a much better sound quality than the Toyota factory setup. Using Siri on my iPhone, I can control everything I need through the GROM USB3, from making phone calls, to choosing music, etc., without ever touching the phone. Did I say the unit is Brilliant?!

    Speaking of brilliant, Skot at Cushie Audio is fantastic to deal with. He’s informative, knows his stuff and will bend over backwards to assist. He was even willing to cannibalise his wife’s car to get a kit sent to me if i needed it in a hurry…brave man indeed. (In the end I was happy to wait a week and save him from any domestic concerns!)

    Thanks to Skot and Cushie Audio for helping me bring the Landcruiser up to date!

    After installing an after market radio in my 2005 Jeep Wrangler and being very unhappy with the look, I did some Googling and came across the GROM units.
    I e-mailed Cushie Audio with a bunch of questions and they were extremely helpful and answered all my questions with recommendations. I ended up buying the GROM USB and the Bluetooth adaptor.

    Plugged it into the back of my stock radio and it just worked. Now my Jeep looks totally stock but has a very modern infotainment system. I have Radio, CD, Cassette, USB and Bluetooth streaming.

    I wish I’d found this before installing the after market unit but at least I got there in the end. I would highly recommend this unit and Cushie Audio to anyone looking for a perfect update to their infotainment system.

    I installed the GROM USB3 in my 2011 Mazda 3 SP25 so I could use my IPOD Classic in the car. The installation was very simple and the installation instructions easy to follow. Skot was very helpful with all my queries and answered my emails very quickly :). I have lost no functionality in my car and all the factory stereo items such as the 6 CD stacker, Bluetooth audio and phone connectivity all work perfectly fine with the GROM installed. The factory steering wheel controls also work with the GROM.

    The GROM essentially works as a CD stacker. So it’s best if you have playlists on your IPOD and then just use the GROM to select the playlist that you want to listen to. You can also put the GROM into simple mode and then manually control the IPOD so you can choose exactly what song or album you want to listen to. It’s a great alternative for those with older scars that have no IPOD connectivity.

    I’ve just installed GROM USB3 with the Bluetooth cable option in a 2006 Liberty wagon with the MacIntosh stereo.
    The device is exactly what was advertised and the best solution I could find to get current tech working with older tech.
    Very reasonable price compared to lesser options or replacing the lot and very smooth purchase and delivery.
    I’m no sound tech or installation guy and removing dash bits as necessary isn’t super easy. Actually connecting up the device and “going live” was the easy bit. I found the instructions were really clear . The advice and suggestions from the very helpful Skot, a few videos both on the Cushie site & You Tube, plus those instructions and it’s all done.

    Great product, installation you can easily do yourself. Purchased for a 2004 Subaru Outback. The sound quality is excellent, I can’t stand the interference that FM transmitters get. Pretty much plug and play, deciding where to mount the unit was the hardest part! It’s a much cheaper alternative than replacing the whole HVAC/head unit and both phones iPhone and Android have no dramas which isn’t always the case.

    Quick Tip: ensure the harness is all the way in and firmly connected to the head unit. I installed and tested the unit (worked fine) the main harness dropped out when I reinstalled the head unit, which resulted in me having to pull it out a second time, albeit much more proficiently.

    I recently purchased the GROM BT3 for a 2006 Liberty 3.0 with a Mcintosh headunit. It worked well accept for the hang up or song down button on the steering wheel did not work. We switched it over to the GROM USB3 with the Bluetooth dongle attachment to which the down button functions as it should and will go down in your song list and also hang up calls.

    If you own a Subaru Liberty with a McIntosh headunit you SHOULD buy the GROM USB3 with the Bluetooth dongle and NOT the GROM BT3, it works much better.
    Great product would recommend highly.

    Skot the owner was also very helpful with trouble-shooting and was happy to organise a swap for the USB3. If anyone has any problems he is very quick to reply and will sort any issues you run into.

    Purchased a USB3 for my 2007 Subaru Liberty. Simple install. Easy to use and does everything you would expect Bluetooth and USB input would do in a modern car. We have any old iPod connected for music and Bluetooth for our phones. Music automatically stops when a call comes in and then resumes when you finish the call.
    This was a much cheaper option than replacing the head unit in the car which as the Radio and Climate control are in the same panel, requires you buy a special JDM HVAC control unit and then a blank for a double din head unit. This alone was more expensive then the USB3 from Cushie.

    My wife needed Bluetooth for her 2008 Honda Civic Vti, to facilitate handsfree control of her mobile phone, prior to the law changes about to be implemented by the Queensland Government. Skot was amazing, he talked me through the whole process, was there on the phone during installation and made sure everything was going to exceed our expectations. I can’t recommend Cushie Audio highly enough; quality from start to finish!

    I purchased a GROM USB3 with Bluetooth for my 2007 Mazda 6.
    After spending a week with Australia Post it arrived. Instructions looked daunting at first but after a few minutes of reading and a couple of bundies I got stuck into it.
    Install was very easy. Hardest part was removing the head unit. If you have small hands, you can plug the cable into the rear of CD player. I’m not that lucky.
    Paired my iPhone to the unit and I’m up and going.
    Sound for music is crystal clear, phone calls were clear with no lag, everything working from control buttons on steering wheel.
    Awesome product, Great value. Was looking at over $1400 to get the same product (Bluetooth) for the car. $1290.00 for a new aftermarket head unit kit, $200 for head unit. $360 was a steal.
    Skot from Cushie couldn’t do enough for me with tech advise before and after sale. Cheers guy’s.

    This is a great product! I thought I would need a technician to install it yet, with the aid of a simple Youtube video and great help from Skot from Cushieaudio, I was able to install it into my 2007 Lexus RX350 myself. I now enjoy streaming music and audiobooks from my phone to my car stereo. I recommend this to anyone with an older style car!

    GROM-USB3 for 2006 Subaru Liberty with factory GX-203KH Kenwood Head.
    Easy plug-in install, works well and sounds great. Car did not originally come with CD Stacker Unit but factory head still supports all required functions. Currently using 8GB USB stick with music stored in 6 folders to emulate 6 selectable CDs. Although the factory head track number display is limited to 2 digits, the GROM-USB3 still plays all of the songs contained within folders which have more than 99 tracks. Highly recommended product.

    Grom USB3 HON1U3 to suit my 2002 GL1800 Goldwing

    Great product to replace the 6 CD stacker unit. Am using it with a 64 GB USB memory stick and works great. Music quality is very good, and it picks up at the last track played when stopping and restarting the audio system. Am limiting each CD folder to 99 tracks, so with a capacity of 6 CD folders, I can now have 594 tracks of music, instead of just what you would have with just 6 CD’s. Love it. Have not tried it with my iPod or phone, but I don’t think that I need to.

    Purchased for my 2003 Subaru Liberty with the factory GX-201KH Kenwood head unit.
    Great service from Cushie – prompt shipment and good communication.

    The GROM USB3 with BT dongle works great in my Subaru, just plug it in and you’re finished.
    Installation took about an hour, though I was taking my time and being quite particular about where I ran the USB extension cable and BT dongle microphone cable.

    Playback via USB/BT for audio is easy and sounds great.
    Bluetooth connects seamlessly and call quality so far is great with no echoing etc.

    Highly recommend this product – great alternative to spending hundreds and hundreds of dollars on a new dash fascia panel to allow fitment of a $200+ standard DIN size stereo only end up with the same features the GROM USB3 with BT provides. It’s also quite nice having modern features while retaining the ergonomics of the factory head unit’s button/screen layout.

    Thanks Cushie Audio!

    I bought the USB3 for a 2005 Mazda 6. Installation was difficult – my car needed soldering/modification to the radio PCB to enable the auxiliary input used by the USB3. This kind of install is not for the faint of heart.

    In terms of usage, the USB3 (with BT dongle) works reasonably well: good audio quality. There is a loud “pop” when the Bluetooth connects but is otherwise great for audio/music. The microphone works well enough but background noise is a problem in these older, noisier cars. The biggest issue I have is that sometimes the BT dongle doesn’t work at all: I have to turn the ignition off and on again to get it to pair. This happens about every 1 in 10 times. It’s very annoying, and is a black mark against an otherwise good product.

    • HI Charlie,
      We appreciate your feedback. Unfortunately you are one of the unlucky ones.
      The Mazda 6 in your year range is the only car needing a modification. I hope you were made aware of this before your purchase.
      I have only been operating Cushie for a month now but I have been installing Grom units for years. I have done this modification twice myself and you’re right, if it’s not your sort of thing it could be very daunting.
      As for your bluetooth issue have you deleted your pairing and started again or tried another device?

    The perfect accessory for anything you can connect it to! installed in 15mins in to my 1996 Volvo 850, this brings the radio on par with other aftermarket radio Bluetooth units, without losing the classic lines that the designers wanted the dash to have.

    highly recommend the Bluetooth adapter.

    Excellent service from the Cushie team as well.

    Easiest thing iv ever had to do. Install literally took me 15 min. Just need to add a momo wheel for the misses and its set.
    Just has a slight issue of not being recognised if you let the car do a full startup test, but if you just jump in adn turn it right on, it works fine everytime. Not sure if a wiring issue.

    Regardless, will be buying again for any car that i have that needs it!

    Works great with my 2006 Subaru Liberty with the McIntosh sound system. Sound quality is good, calls work well and it integrates with my steering wheel which is an added bonus. Bluetooth connects to my phone quicker than my Dad’s new Mazda 3!

    The only issue I see is that the extension plugs seem to be easy to pull out. I hope I’m not opening up my dash in a year to put them back in after a year rattling around in my car, but this seems a low risk. I might suggest putting a spot of silicone on them to ensure they don’t come out before installing if you’re worried about that.

    Got a Subaru Outback 2006, this device is well worth the price, audio quality is fantastic, there is the odd time that the audio pops or cuts out for a split second, but I believe that may be my iphone cable as it’s not a genuine Apple product.

    I would still highly recommend this to anyone wishing to upgrade.

    Forget about the extra Aux Input & USB Charging hybrid extension!

    I purchased this product, together with the Bluetooth Dongle Extension and the hybrid Aux Input & USB Charging Extension. This was an excellent product. Installation was very easy. The only annoying issue is that the single AUX-IN connection gave a really muffled, poor quality sound when songs were played (with the hybrid Aux Input & USB Charging Extension connected to my phone), but if I connected my phone to both the AUX-IN port and the USB port at the same time then the sound quality returned to normal.

    I would advise against buying this hybrid extension since you would need to connect it to both the AUX-IN port and the USB port on your phone for quality music, because a single AUX-IN connection on this hybrid extension did not seem to provide enough electrical current. Instead if you want AUX-IN, buy the Auxiliary Input Extension without the USB port attached. Or if you want an extra charging port, just buy the USB cable.

    If you are simple-minded, don’t bother having the AUX-IN connection because either bluetooth and USB mode has more functionality and they worked very well!

    Another minor issue is that the process of changing songs was fairly laggy at times if the stereo was in USB mode, either due to the DashLinQ software or my car stereo system. No such problem if bluetooth was used though!

    Beside those nitty-grity things, I am happy with my purchase.

    For those who have desperately used FM tuners etc, this kit is an absolute boon!

    Great bluetooth reception, giving crisp clear audio all the way. The microphone for the hands-free dongle is great, and pics up audio very clearly. Installation is very easy (I’m in no way a mechanic – however, videos were hard to come by, but I did find a couple).

    The design of the unit is very good. Fits easily into the rear space behind the existing radio. Design thoughts such as automatically resuming music when I return to the car (I use my iPhone to stream music to my car audio) makes this a very desirable product!

  66. 5 out of 5

    Fantastic apart from the occasional drop out. Value for money and great solution for those who like to stream their own personal music or radio stations. This product does it all so seamlessly, to now have hands free phone connection within my car is such an added bonus. I priced a car stereo to replace the vehicle’s original stereo and it was going to cost me $1600, so $300 is cheap as chips.

  67. 5 out of 5

    I really appreciate the thorough service in making sure I ordered the correct unit for my car.

    The ordering system initially automatically delayed delivery because one of the non critical components was on back order but this was quickly rectified by the support team.

    Installation was straight forward but getting the earth wire connected to a suitable ground was surprisingly difficult in this car. I ended up drilling a small hole for a Philips head screw and attached a terminal connector to the rear of the radio unit (making sure there was no circuitry behind the hole! ) to ensure a good earth. This is no reflection on the product – more on the car / stereo itself.

    The Bluetooth and the iPhone lightning interface worked seamlessly with the unit.

    Really happy and thank you!

  68. 5 out of 5

    Overall this unit seems high quality. I no longer use the factory radio, I just use my phone music app or radio app, via bluetooth or USB. Exactly what I wanted. Thanks Cushie Audio

  69. 4 out of 5

    Gaining access to the stereo unit was a little bit involved though a few YouTube videos helped out. A dedicated video on the website for each car model would be useful.

    Once installed was very impressed with the sound quality (the same as if playing a CD) and the functionality. Particularly like how the unit will automatically start playing again from the same spot when interrupted by incoming calls, channel changing or engine start or stop.

    Definitely superior to FM tuner type devices and a lot safer as you are not constantly retuning or having to put up with low quality sound.

  70. 4 out of 5

    Great product. Fast shipping. Only problem is USB integration doesn’t seem to work well with this stereo (the stock stereo for this car). AUX, iPod and Bluetooth works great. Bluetooth hands-free works great with the steering wheel controls. The AUX volume seems a bit low. Overall a great product.

  71. 5 out of 5

    Easy to install (with a bit of simple YouTube research on how to dismantle centre console). Took about 1/2 hr in total.

    Scan button doesn’t work, but everything else works as advertised. Handy feature is to store playback position of individual playlists. Be careful not to include non audio files in the folders or it may cause issues. Only con i see is that it could have been a bit cheaper – say $150 or so instead of the $230 i paid.

    It took a lot of effort to find this device but it was absolutely worthwhile. The unit provides exactly the functions I was looking for and offers expandability to cater to future devices. This item enables me to listen to music whilst riding via a USB stick plugged into the unit, but also enables me to listen to music and recieve voice navigation commands from my Sat Nav unit via the EXT connection if I am on a longer trip. Excellent flexibility of operation. The staff at Cushie Audio have been very helpful throughout, providing fast, efficient and courteous service at all times.

  76. 5 out of 5

    Definitely worth the $$$!

    Picked up an Accord Euro over a month ago and was immediately looking for a decent aux adapter. Was going to settle for a basic 3.5mm adapter but, after seeing the features of the GROM USB3, couldn’t pass it up.

    Very easy to install and tucked away neatly with just a USB cable sitting in the centre cubby hole. Charges my iPhone 6 and auto pause/resume on ignition cycle (or switching modes) is an excellent feature. Steering wheel controls work well in all my music apps including Soundcloud.

    Sound quality is decent and a good volume compared to FM/internal CD. Navigation voiceover is clear while music is playing too.

    I initially had an issue playing sound from another app but simply changed it from advanced mode (DISC 2) to simple mode (DISC 1).

    Definitely recommend this product and received excellent service from Cushie Audio who were quick to double-check my vehicle model to save being sent the wrong unit/cable.

    A couple of days ago I received my GROM-USB3 interface unit and Subaru specific cable along with the Bluetooth dongle GROM-BTD and microphone. I installed it in my MY06 Subaru Outback yesterday (dead easy) and I’m over the moon! Previously I was using an iSimple FM interface that simply allowed me to listen to music from my iPhone without a whole heap of quality. It always had connection and distortion problems and had recently become unusable.

    I have a pair of Morel component speakers and a Focal Bomba subwoofer installed (about a $800 altogether) but it is only since installing the GROM that I can’t stop smiling. The music has cleaned right up and the sub now sounds like a really nice sub. In a word, awesome!!

    I thought I’d drop you a line to say that almost 3 years later I’m still very happy with my Grom USB2 (U3i) installed in my 2004 Honda Accord Euro. Best upgrade I ever made. I recently bought an iPhone 6 and was a bit concerned when I couldn’t get my BTD Bluetooth to connect (and there are plenty of complaints about iOS8 and Bluetooth). But after trying numerous things I finally read the troubleshooting guide and discovered I just had too many devices paired, so easily fixed and now works perfectly. Anyway, just wanted to let you know what a great product you guys have and I recommend it to all my friends 🙂

  85. 5 out of 5

    Install very easy, I am not used to not having to cut any wires to do work like this. Works well, sound is great. I should have read the FAQ’s a bit better as I thought I would see track name and artist information on the screen, but just re-read this and found this is not available on Toyota radios with navigation, other than that very happy with the kit.

    Easy install as the CD changer under the front passenger seat on extn cable. Plugged straight in.

    The Bluetooth Dongle & Handsfree Microphone (BTD) works a treat and manages calls fine, good sound quality and best of all, it manages BT music streaming from a Samsung Galaxy S3 with ease from the native music play app.

    Initially the Samsung Galaxy S1, S2 Cable (5Ft) wouldn’t plug into the GROM unit. It appears that the orientation/location groves on the mini-DIN metal outer, don’t start from the edge (like the BTD), but start part-way in the metal outer. Not using the cable now that the BTD kit does the job.

    Continuing to “play” with the other features as time allows.

    Very impressed, especially with the BTD.

    I have the GX-204KH unit in my Subaru Liberty 2008. The in-dash 6-disc player stopped working a few months ago and was going to cost several hundred to repair. Enter the GROM USB unit at half the price!

    Installation only took 1hr to complete, and sits in the corner of the glove box. Only had to drill a small hole to allow the data cable to go through from the stereo to the unit. Very simple and no special tools required.

    In USB mode, the unit acts like an external CD changer for this model, and maps folders on the USB stick to discs – very cool, and the quality is CD quality, as long as your MP3’s are of a decent quality themselves. The latest firmware update supports FLAC also which is great.

    The best part is not having to switch or carry around CD’s anymore, that has GOT to be safer!!! Convert and put all your CD’s on a tiny USB stick and away you go.

    A great product and highly recommended.

    The GROM Audio unit gives far superior sound compared to the FM transmitter it replaced.

    The integration of the Bluetooth phone and music player with the steering wheel controls is great. I can use the wheel controls to navigate to the next and previous songs in a range of music apps, including streaming service Grooveshark. The next and back buttons on the steering wheel are also used to accept or decline an incoming call via the Bluetooth connected phone.

    When purchasing the unit I found it difficult to understand which adapters I would need. With my Android phone, really all I needed was the Bluetooth dongle, but I purchased 3 other adapters that I may never use. Also the micro-usb adapter used with many Android phones, was disappointingly not an option when purchasing the unit.

    The GROM unit sits in my glovebox and is attached through the back of the glove box to the stereo. The Bluetooth microphone cable goes out the back left of the glove box and is hidden under the edge of the windscreen, and comes out at the front of the interior light.

    Some of the set up instructions were difficult to follow, particularly the parts that said to press buttons on the stereo that don’t exist, but with some trial and error I worked it out.

    All in all I’m really happy with my GROM Audio unit. Now I would just like to buy a charging dock that plugs into my light plug, rather than running a cable from my glove box.

  89. 5 out of 5

    Great product, I am very happy with it (first check that your radio firmware version is supported).

    I Purchased:
    1 x GROM Mazda USB3
    1 x MiniDIN to MicroUSB Samsung Galaxy Cable
    1 x MiniDIN to 3.5mm Auxiliary Cable
    1 x Bluetooth Module with Microphone

    Support questions were well answered, very quickly. The samsung galaxy cable (MiniDIN to MicroUSB Samsung Galaxy Cable) only works with the samsung galaxy phone, it is not guaranteed to work with any other phone that uses the same MicroUSB connection type (eg HTC Sensation phone does not work using the MiniDIN to MicroUSB Samsung Galaxy Cable – it will charge the phone but not playback any audio through this cable, it will playback audio through the bluetooth module only)

    The best option is to use the USB cable that comes with the phone that you want to use, plug it into the USB port on the GROM and audio playback should then be through the usb cable. The bluetooth module works perfectly for phone calls. A USB memory stick in the GROM USB port plays MP3’s perfectly.

    Mazda RX8 2005 with Bose 6 Disc CD Stacker Installation: Either remove the dash and the head unit or remove the glove box to get to the rear of the head unit. Remove the glove box from the left hand side of the car, reach in to the right and remove the aerial cable from rear of the head unit, plug the wiring harness in and plug the aerial cable back in – have someone with very small hands! – then continue with setup.

    Very happy with the end result, I didn’t end up needing the MiniDIN to MicroUSB Samsung Galaxy Cable (only because it doesn’t work with my HTC Sensation phone).

    Very quick to install once you know how to remove the Radio/CD Changer unit – good pictorial guides for this operation available on the web; GROM box can be conveniently velcroed to the back of the glove box; works like it should – only issue so far is that sometimes it seems to hang on the odd track when using the USB stick input. Great solution!

    I was looking for an iPod adapter for my Mazda and found Cushie Audio through a Google search. After researching their website I placed an order and found their customer service excellent. The installation was easy as all I had to do was remove the glove box and plug in the data cable and go from there. The only thing I would have liked would be that the song title and artist’s name be displayed on the CD player. I do not know if this is because of the unit or the CD player.

    Cushie Audio Comment: Unfortunately the Mazda 6 radio lacks the ability to display song and album information. All GROM Audio kits have the ability built in to display text but it comes down to the capabilities of the stereo unit. Nevertheless we hope you are enjoying using the car kit.

    Very impressed with the USB & Bluetooth Car Kit (U3i-SUB08) kit I bought. Very simple to install and worked straight way without any issues. The sound quality is excellent and work with an iPhone 4S without any issues. The only comment that I would make and it’s on the support pages is that you can’t use the USB connection and mic from the Bluetooth as a handsfree kit. You have to use the Bluetooth connection to make calls. It’s a very very impressive bit of kit for the money and I’d recommend it.

    Very happy, very easy to install and works well. Using with USB stick full of MP3’s, sound quality is no different than MP3’s converted to audio and played on CD player.

    The kit was a snack to put in and simple to set up. The audio quality was spot on, it had no static and had something called ‘bass’ which the FM transmitter I have been using lacked badly in. The original controls on the stereo control the unit welI. I love it!

    Positive outcome. For those who have a Mazda 6 (this one is a 2003 Sport Luxury) and have the Bose system you know what a pain it can be to alter the makeup of the audio system to get iPods and iPhones connected. There are a few options out there – DVD GPS combo players etc that get fitted into the upper glovebox in the dash centre but they are all very expensive and have to be brought in from OS (Ebay etc).

    This is simple – it plugs and plays (you do lose the CD player but thats a dying format anyway) – what I ended up with is Bluetooth, Direct iPod, a 3.5mm universal in, Handsfree Mic and a USB connection. All fitted using just a little double sided tape and felt padding – no screwdrivers in sight and just a torch to help my sight a little. For anyone wondering if it will work for them – worked fine with both 3GS and 4S iPhones for all functions. Fitting is simple – Mazda 6 glovebox clips out – theres the back of the Head Unit – plug it and find a place you can hide all your wiring. I ran it back under the centre console with all cords out the cup holder section (which can still be closed to hide it all).

    Our phones have GPS, Music, Videos etc so any other more expensive devices would have been a waste of time anyway – this is perfect – 1 device, 1 format, 1 interaction for updates on a home PC (Tom Tom iPhone app Maps etc) good sound and off you drive.

    EDIT: The issue of CD Player no longer functioning only affects some earlier models of Mazda 6 2003/2004, this is not a wide spread issue, almost all Mazda 6 radios are unaffected. The radios in these vehicles are subject to other issues as well some of which can be fixed. For more information please see:

    Better than others I’ve used! I finally had this installed into my 2007 Honda Accord Euro Luxury with Factory Fitted SatNav yesterday, after purchasing it late last year. I purchased this along with the iPod cable, USB cable and bluetooth extras. I can’t comment on ease of installation, as I paid for it to be done (partly due to the bluetooth microphone being placed on the front pillar, which could interfere with curtain airbags, and partly due to not trusting myself to not break anything…) but it did take longer than my last system.

    After getting the car back after installation I found the setup a little more complicated than other systems, but it was only a matter of timing when changing modes (it’s all in the instruction manual, I just had trouble hearing prompts and switching modes in time.) Once it was all setup it worked like a breeze. Doesn’t interfere with other functions of my car stereo like other brands have previously. I have retained use of my SatNav and internal CD changer (as noted, more than I can say for the X-CarLink I had in my Mazda previously.)

    Sound clarity is as expected, CD quality from what I can tell. Control is fine, all functions on the steering wheel working. All in all, happy to have iPod direct back. Bluetooth works fine, although ring tones play quite quietly and with poor sound clarity (not that it matters.) Audio is somewhat delayed, but this is to be expected.

    One interesting thing, that pleased me quite a bit, was that I could control bluetooth audio through my steering wheel controls! Very handy. One last point, contrary to what else has been said here, my iPhone DOES pause the music playback when I turn off my car.

    Great product… in fact almost perfect. I have both my iPhone and iPod connected to the device simultaneously. Use the iPhone for calls while the iPod connects for music. The Handsfree operation of the iPhone is really good, and all the callers say they can’t even tell i’m in the car talking. Have one minor issue with the plylists in the iPod but I’m trying to resolve that.

    Perfect Product. Easy to use, Easy to install no need for any technical support as the manual took you through step by step on how to complete the installation and where to connect things. It works brilliantly with the steering controls and the phone quality is crystal clear on the Bluetooth.

    Would recommend the product and the sales and service from Cushie Audio to anyone.

    I’ve installed the device and I’m extremely happy with it. Excellent product!

    I have a Subaru Liberty 2006 2.0R Auto with GX-203KH head unit, I purchased the GROM USB with Bluetooth option because I wanted the flexibility to have copious amounts of music on demand with the option of playing music from an iPhone or IPod, plus hands free phone capability. I have had the unit in and working for about a month now and can report that it ticks all the boxes and more.

    When I first tried installing it the software turned out to be incompatible with my head unit, however after a few emails, a bit of waiting and some excellent support, I received an update and my GROM USB sprang to life. The USB supports my WD 500GB hard drive giving me all the capacity I want. I used a freely available HP formatting utility to format it FAT32. The sound is CD quality in my opinion.

    Bluetooth audio playback is excellent and a handy feature. Most devices pair easily, including my youngster’s Hauwei Android phone. Bluetooth hands free phone functionality is excellent as well, with audio muting automatically when a call comes in. I haven’t yet fully explored functionality of the iPhone integration due to a fault with my 4S but from the brief testing I have done with family members’ 3GS and 4, the audio quality and functionality do not disappoint.

    Switching between modes took a little getting used to but is now a breeze – just press FM and CHR in quick succession to activate mode change, and use the up/down buttons to change modes. The only function that should work but doesn’t is the Scan button, which should enable jumping 10 tracks at a time. I’m sure this will be fixed in a future upgrade though.

    Installation was pretty straightforward and the unit fits nicely in front of the transmission lever and below the ashtray. All in all a very worthwhile upgrade to my car stereo – highly recommended.

    Fast delivery and good integration with my Toyota Aurion. Ordered the unit four working days before Christmas and it was shipped immediately arriving before Christmas. Well done! The GROM Audio unit installed well and works as advertised with the USB and Bluetooth phone connection integrating well.

    Couldn’t be happier with the Mazda iPod, USB & Bluetooth Car Kit. My main problem was removing a messy older hands free kit. The GROM unit plugged straight into the back of the stereo and sounds great. I put the unit into the glove box and I have access to all the cables etc to change USB drives or plug in my ipod. Bluetooth unit works a treat, just needed to reboot my Nokia phone and away it went. Couldn’t be happier.

    Great experience and very happy with my purchase. Great pre-sales support via live chat and couldn’t be happier with the product. Both the U3i and the optional Bluetooth module work perfectly in my 2005 Mazda 6 GG series 2.

  110. 5 out of 5

    Great product. Purchased for an Aurion Presara 2007. Easy to install, great support via phone if you need it, and sound quality is excellent as expected. The only negative is that the SatNav screen thinks it’s playing a normal CD, so no song title, artist, etc. That was via iPhone, I’ll try USB stick next.

  111. 4 out of 5

    Pretty happy with the product so far. The only thing I’m not totally happy with, is the fact that I can’t answer calls whilst listening to the radio. I only hear audio from my phone (either music or phone conversation) when the stereo is in the ‘CD/AUX’ mode, so if I get a phone call when I’m in ‘Radio’ mode, I have to quickly change modes on the stereo and then answer the call.

    This is easy enough to do via the steering wheel controls, but if there was a way around this issue, it would be a flawless system.

    Fast delivery and Friendly Service. Couldn’t fault this product a quick phone call to Cushie Audio and the lady knew exactly what i needed and what suited my needs. I don’t have an iPhone like all the other sheep. Instead i own a HTC Incredible S its powered by USB so it made sense for kit supplied that can play my music on my HTC mobile via bluetooth and charge my phone via the USB. And yet also be a handsfree car kit. The youtube video clip came in really handy to better understand how to take apart the factory OEM console area from a Honda Accord Euro Luxury 2005 without braking the fragile plastic. VERY IMPORTANT TO ALL HONDA ACCORD EURO 03 – 07 OWNERS ! ! !

    Slow start but finished off well, I want to thank everyone that assisted in getting the Bluetooth option working correctly in my Mazda. Thanks for the quick response and release of firmware. Special thanks to the local crew (Mary & Justin) who kept me informed whilst we worked the issue out. A+ for effort.

    I have a September 2006 Mazda 6 Luxury Sports (GG1032) with the Bose 6 stacker MP3 compatible head unit that was introduced just before mine was made (it has MP3 printed on the left side near the 6 CD sign). Forget the Yanks: I was interested in gaining the extra features that the GROM Audio USB iPod AUX box would give but was concerned that the manufacturer, GROM Audio (in the US), was unable to tell me definitively whether it works on the MP3 version of the Bose head unit. In fact, GROM Audio was surprised that we Aussies had MP3 compatible head units as early as my car. They said that in the US the MP3 head unit was not introduced until 2008. They suggested I check behind the head unit, if the head has the two CAN wires (CANH and CANL), you will have to use the GROM MAZ8 USB unit instead of the 2002-2008 unit. These CAN wires are part of the other port on the back of the radio (the one that isn’t the AUX port that the USB/iPod unit connects to). My checking on my car confirmed that this spot can’t be seen without removing the head unit, so I decided that I wouldn’t be doing that in a hurry.

    I put a message up in the forum but despite 170+ lookers, no one could confirm compatibility and I wasn’t prepared to pay postage from America on a maybe.

    I then noticed on the GROM Audio web site that there was an Aussie distributor (Cushie Audio). I went to this site and was delighted to see that there was a direct chat function. I told Justin (who was great) my worries and he immediately solved them, assuring me that the MAZ02S data cable and U3i-MAZ box combination works on my model. I ordered them then and there (for pretty much what the Americans were charging including post) and they arrived within a couple of days.

    Installation: This was dead easy. I removed the glove box (slip the rod off the left hinge and press in the right side and it lifts out), then I felt around the back of the head unit for the socket (which is next to the antenna) and simply clicked in the data cable (and it does make a clicking sound when it is in properly).

    I could have simply ran it to the glove box but I wanted a more professional install, so I clicked off the screw cover from the passenger side foot well of the centre console and removed that screw and then removed the two screws in the base of the arm rest to loosen it all a bit (the armrest screws are under the piece of felt. Just lift it out and put it back once you have finished installing). Next I ran the wire along under the edge of the console back to just below the plastic “grill” in the base of the armrest. I cut the grill on three sides and bent it up enough to pull the end of the plug up through with pliers and then bent the cut edge of the grill back under it and back to its proper place. (Note: The wire was only just long enough, but did reach.) I now had the plug firmly positioned inside the lower armrest bin. I put three layers of double sided tape on the U3i-MAZ box (to ensure the coin tray wasn’t in the way) and attached it to the inside wall, facing up.

    Setting up the folders the way the box requires was very simple and it played first time but I had a couple of glitch events at first. Occasionally the box wouldn’t recognise the files when I turned the car on and I would have to set the head unit to CD and then back to the box again before it would play (easily fixed but annoying). It also didn’t display the song playtimes count on a couple of occasions. The good news is that GROM Audio is constantly working on the firmware. I went back into Cushie Audio’s chat and discussed it with Justin and he suggested I download and installed the latest firmware patch (version 28) which was quick and easy to do by following the website instructions Justin directed me to. This update did the trick.

    The finished product: No one would ever know it is there. I don’t need the USB cable, my thumb drive plugs straight into the box and the box is so small that there is still plenty of room in the armrest bin for CDs, my iPod and the iPod cable to live happily in there too. It plays all of my MP3 and m4a files (but not wav files) and they sound fantastic. I have full steering wheel control. Sadly, the LED display still doesn’t show the singer and title details in this model Mazda but it does indicate the disc number and song number plus counts the playtime of the song. Hopefully a future firmware update will provide the singer and song details (hint hint GROM Audio).

    As you can see from my story, Justin at Cushie Audio took all the uncertainty out and made the whole process easy. Many thanks Justin.

    Very Good. 2007 Mazda MX5 with factory standard Bose system. Very easy to install. Took about 20 minutes. Everything works well. Bluetooth and USB for iPod. Works perfectly using steering wheel controls. Always connects without any issues as advertised. Is a good choice for adding to your car. I would choose this same system again.

  116. 4 out of 5

    Purchased this unit for a 2008 Aurion Presara. Installation was simple, needed to read the manual to be able to get the iPhone to play music and control via steering controls. VERY happy now that it is working as it should, even great that it charges the phone as well. Job well done for an innovative products.

  117. 4 out of 5

    Really happy with the box. Works very well as described.

    My only 2 things.
    1. My audio is not that loud. It seems like I need to turn up the volume really loud to hear it properly and I’m unsure why. When I switch it back to Radio, or CD it is much louder than when on Bluetooth.
    2. Would be great if you could force the audio to start from the Honda Controls, rather than having to start the iPod/audio from the iPhone first.

    Great box but sound not that loud.

    Fantastic Device! Got the U3i-MAZ unit and the MAZ02S cable. Installed it in the 2006 Mazda6 in 10 minutes flat. All I did was take off the glove box (as per comment from the person previously), reach behind the stereo unit and connect the cable (the connector is right next to the Antenna cable/connector). I decided to leave the unit in the glove box. It sounds great and it works with the OEM stereo controls and the steering wheel mounted controls. Given the price, this is a no brainer buy! I also chatted to Justin online prior to purchase. Asked him more than my fair share of questions and all were answered properly. All in all, a fantastic product and a fantastic buying experience.

  119. 4 out of 5

    Near perfect… Works perfectly – never had an issue connecting to bluetooth (for calls & music), and I love being able to control the iPod through my car steering-wheel controls.

    My only gripe – I’m sure I was told before buying the unit that the iPod would automatically pause when the ignition is turned off…….. It doesn’t. It does pause when turning the stereo off or switching the stereo to CD or Radio mode, but not when turning off the ignition. I’ve got into the habit of turning the stereo off before I switch off the ignition. Obviously this is only an issue for iPods that are left in the car (not iPhones that are unplugged & taken with you)

    Apparently its an issue unique to the Honda Accord Euro and VW Golf – Tech support said “it’s something we know about but don’t have a fix for it”. Hopefully will be fixed in a future software update.

  120. 4 out of 5

    Very Happy. It was a breeze to install, just had to look up how to remove the stereo from the dash, then it was just a matter of plugging it in and music playback worked no problem. The bluetooth isn’t working properly yet, but looks like I need to update the firmware.

  121. 4 out of 5

    Great service, I made some mistakes with my order but had help nearly instantly and all was figured out. The unit works as advertised. I have a 2005 Mazda 3 SP23 and am using the U3i-MAZ it was a simple matter of plugging it in and away I went.

    I’m also having some recognition issues like Andrew mentioned in his review so will try the firmware update and see how I go. Apart from that, very impressed. Thanks Guys.

  122. 4 out of 5

    The service was great, Mary was quite helpful. The device was super easy to install. I Have a Mazda 6 2003 and did not have to make any changes, just plug and play. However, I had to download the latest firmware from the US site as it was more up to date and that fixed a problem with recognition.

  123. 5 out of 5

    Hi guys! sorry for the delayed response, been flat out busy and never had any time (or daylight) to install. But I’ve finally got round to installing it today. And the product is just AMAZING! Awesome sound, works like a charm, and looks very sleek. Thank you, thank you, thank you. Good sound, good looks, great service. If your looking to get some extra functionality into your lexus without the hassle of a whole new headunit/speakers/amp problems. This is the product you are looking for!

    It looks great, very sleek, so easy to install, i did it myself and it took me about 40minutes with no experience installing car sound systems. The sound quality is superb.

    The Cushie Audio staff are helpful and can be reached very easily if there are any problems. Keep up the good work guys! I will be recommending this website and this product to everybody i know!

    Great Product & Excellent service & supports from the Cushie Audio. It is a great and cheapest alternative audio enhancement for old BMW. It is easy to install and provides an extensive range of supportive devices for the audio system, especially the bluetooth adaptor. Overall, I’m extremely happy with products, and for most, the service and support provided by the Cushie Audio.

  125. 5 out of 5

    Great Awesome! Just wanna thank all of you at Cushie Audio on this item I brought. I will tell family and friends about your products. THUMBS UP!

  126. 5 out of 5

    Very happy with my purchase, looked up a youtube video on how to install for my car and while there was minor differences it was still extremely easy to install. Sound is great and well worth the money. Thanks!

  127. 5 out of 5

    Its awesome with room for improvment. I think the integation part still needs work!! but sound quality and value for money is awesome you will not find anything better…

  128. 4 out of 5

    Not bad, has difficulty connecting to my Nokia E71. Sometimes does not come on when the car is turned on so once the car is running there is no option to select it to play music. Turn the car off an on again its fine. Other than that easy to install and concept is great.

    P.S. saw plenty of install tips including stereo removal procedure but having large hands found all too difficult. In the end I simply popped the glove box out reach in and plugged the cord into the back of the CD unit. May only be an option in the RHD models but is very easy.

    Excellent Service and Product. Having done my research. The GROM product offered by Cushie Audio was the best choice for my 2006 Mazda 6 with MP3 CD option. The chart offered by both Cushie and GROM was unclear about which cable would work in my Mazda. I contacted Cushie support, they were extremely helpful in working with me to get the right cable.

    For the record the Head Unit in my car:
    Head Unit details.
    Model: CQ-EM4680AK
    Made in: Thailand
    Serial: 505323
