Mazda CX-7 Grom USB3+Bluetooth kit
Here’s a walk through of an instal I did in a 2010 Mazda with MP3 stereo.
It’s a Grom MAZ8U3 kit with bluetooth dongle in a 2010 CX-7
A pretty straight forward gig, though 3 wires had to be tapped in to.
but if you have the earlier model it is as simple as one plug!

Put a towel down to protect everything from the sharp corners

Get that towel under to catch them. But if you dont unscrew the collar all the way you wont be dropping them….
