2012 GMC Terrain not syncing with iPhone 4 after iOS 5.1 update
I'm having problems with my 2012 GMC Terrain SLT-1 not recognizing or syncing with my iPhone. I upgraded to ios 5.1 this past week; prior to this, I had virtually flawless integration of my iphone 4 with my GMC Terrain SLT-1. In the past three days, the iPhone intermittently gets recognized by the stereo but then the dash screen will freeze on a song. Other times, it will not recognize the phone or list no songs in the car's display. I've done a cold restart of the iphone, changed USB cords, re-updated, and then did a complete factory restore of the iphone but no luck. Any ideas?
