So I just got the GS3 and also bought a new car this week (mega awesome week)...a Chevy Sonic. I figured out how to connect the phone via bluetooth once for calls and another time for audio streaming. Everything pairs and connects fine. My only issue is that whatever I stream through the music side of things only comes through on my left speakers. Yes I have played with the settings to ensure something wasnt off. I googled and seen a bunch of people are having this issue with various cars...but didnt see a fix except for one guy who got a whole new stereo. Would love to avoid a trip to the dealer and thought if anyone could help it would be this android community
