I've done a search and haven't been able to find anyone with an issue quite like mine. I have the GS3 running version 4.1.1 paired with my 2012 Veloster with a 2013 factory AV system. I can pair the phone with the car AV system with no problem. If I have the GS3 bluetooth turned on when I start the car, it works and auto connects just fine. However, if I disconnect from a call, receive a text, email, or, simply hit the volume button on the phone, it disconnects from the car AV. The media screen on the car AV system has a Pandora button. With the bluetooth on and connected, if I hit the Pandora button, the phone will wake up, Pandora starts, as soon as the music starts to play, it disconnects from the car AV. I have checked the boxes next to call audio and media audio. After the phone disconnects on its own, I can go back to that menu and the boxes are no longer checked. I am baffled....any ideas?
