OK...this drove me crazy all weekend.....my Pandora and iHeart Radio weren't working. The screen worked fine and showed that music was playing...but no sound. I tried repairing bluetooth....nothing. I restarted the car....nothing. Finally found the solution! Turns out the problem was that the volume was all the way down on my cell phone....which results in no sound on the system!
Oh weird... but at least your iheartradio works. I've had Pandora going for a while now but I never have gotten iheartradio to work in the car. r
