No audio with Bluetooth (Ford Sync) - iPhone 5s
My iPhone 5s is running 8.1.3. The phone has worked consistently with Sync in my Ford Fusion since I got it, until Sunday, when it connected but no audio is transmitted. Music on my phone progresses in time and when I make calls, the other person can hear me speaking, but no audio is sent via Bluetooth. I have already tried master resetting the Sync, and other phones connect to Sync. I have rebooted my phone, deleted the Sync connection and reconnected it and nothing is fixing the audio problem. The volume on the phone is turned up all the way, and there's no volume in the car at any level.
I know a lot of people had trouble with this earlier with iOS 8 but this problem is new from this weekend.
