I always listen to Pandora via bluetooth in my car without a problem. Just recently I needed to use the gps navigation on the phone and pandora seemed to continue playing in the background with the navigation app up front, until the song ended. after some long silence i switched back to pandora app and it said "Searching for Coverage". Will apps not share the data line? I imagine this happened because google navigation was using data to download maps as i went and blocked pandora. Anyone know if i am missing a setting or does the GS3 indeed not share data to two apps simultaneously?
