Since updating to ios 8 my iphone has stopped working with my car bluetooth. Media still works playing music and skipping etc, but when the phone rings I cant answer using the car controls and no audio comes through. Have tried debonding and re-pairing but still nothing. Other phones still work with the car, so I can only assume an ios 8 glitch. Car is a 2012 Ford Focus. Has anyone else had anything similar and managed to fix it?
