If you’ve landed here it likely means your car has the fibre optic system MOST. It doesn’t leave you with as much choice hence the dearer price over the other Grom kits. MOST of them (yes, a pun) are very simple to fit too. Some being even easier than normal cars and gives you digital quality (without relying on NBN!)

 

The future in USB car integration

The GROM MST4 comes with everything you need to make your existing car stereo working like a brand new one, leading the field with near-universal support for any USB stick, drive, or phone – straight out of the box. Fully integrate a USB2.0 port into your car allowing you to control playback through your car stereo or steering wheel controls.

Stream or play your tunes

Offering support for MP3, M4A, OGG, FLAC, AAC, WAV audio files, or just stream your music direct from your Apple or Android device. The GROM MST4 does it all, giving you unparalleled audio quality via a direct cable connection to your car stereo.

Get even more out of your Android device with GROMs DashLinQ app.

It can do it all, even bluetooth (add on)

The MST4 comes equipped with a USB port that connects to any USB drive, Android (prior to Version 9), and Apple Lightning device or the old 30 pin. But on top of that, you can supercharge this unit with an optional Bluetooth Dongle giving you the best of both worlds – enabling handsfree calling via bluetooth as well as audio streaming via A2DP.

 

Unfortunately Grom doesnt show this with the Bluetooth extension in this clip. But it just plugs in and then you mount the microphone and stream away!

    The end result is fantastic but it was a bit of a process to get there. My queries were promptly answered, delivery was swift, installation was straightforward. However I encountered the MOST security issue which required a trip to Volvo for a software patch. Skot was super supportive the whole way and the sound quality and functionality provided by the unit is a joy. (2005 Volvo XC90 2.5T)

    I bought this a couple of weeks ago and it is great!
    The service from Cushieaudio was also great and the unit arrived within a few days too.

All sorted and working perfectly. I visited Tim Dunn at Volvo Penrith and
got a few things sorted out on my car. Difficult to isolate the true cost
of the MOST patch but <$100. Thank you for all your help Skot!
