My car only has FM and a CD player. I used several apps in the past to force a stereo signal into a mono signal so I can trasmit the bluetooth to my FM radio. But none of those apps work with (either) Android 4.0, or maybe just the GS3, I am not sure. (The Mono widget that comes pre-installed does nothing for bluetooth) 
Has anyone found one that works?
