Z - I have a factory set up, and I'm done with the tethered phone. I used to run an iPhone, and Car Play would pop up once I plugged in the iPhone. I went to the dark side and now run an Android phone- so was wondering if using MA1 with Android if Android Auto would work.
When you plug your Android phone in, does Android auto run on your bike? It should. If so then the MA1 will work.
I say wired Android auto should
already work because it will on a stock bike, but I don't know what modifications have been made to your bike. For example Carplay won't run on a completely stock RGS, so something has been added to enable it on your bike (eg. Carplay jumper).
The MA1 will only give you audio through the speakers. If there's any chance that you'll ever want to send the audio anywhere else (like a Bluetooth headset or Bluetooth speaker) then for the same price you can get the AAwireless box instead. It gives you the option of playing audio through the speakers or through a Bluetooth device instead.
Those are both good options if you know that wired Android Auto already works on your bike.
