I have a pioneer avic 7200nex and never had a problem with my bluetooth connection. Today i tried playing music thru my phone and making a phone call, even tho it said it was connected to my phone there was no audio coming thru. The bluetooth audio setting under the home screen was greyed out. I randomly clicked on the pandora app and it actually started playing the music from my phone. How do i get my bluetooth app to work properly again? The music on my phone showed it was playing but i had no audio coming thru my car speakers.
