If you have a Samsung Galaxy S3 and GROM /w bluetooth...
 

Can you use the steering wheel controls?
I have an IPD3 with the bluetooth dongle and can't control it only listen.

I'm able to control it when I use my iphone 4s though which is annoying to say the least.
It shouldn't matter if I use the IPD3 vs the 'android' USB2 grom, once that bluetooth dongle is plugged in things are controlled via AVRCP or should be at least.
