Hello, I have an issue that is just driving me nuts...

I have my S3 paired with my Kenwood DDX419 headunit (which is BT Audio compatible) and I can only get it to work for calls. I check media audio and after a few seconds the phone automatically unchecks it. I've turned off all power saver modes and tried re-pairing multiple times. My head unit also has the latest firmware update... Sometimes when I re-pair it the BT audio will work for like 10 seconds. Ill hit pandora and it will start playing through the speakers but a few seconds later it just turns itself off and starts coming through the phone... Is there maybe an app I can get to force media audio on?

Any help would be GREATLY appreciated!
