I was out and about yesterday when my system shut down. Lost all sound, connectivity, and the screen went black. 2-3 minutes later, the screen came back with "SYNC, Scheduled Maintenance". A bar then showed something that appeared to be a download. When the system rebooted, my iPhone would not pair. I finally worked it out after coming home, deleting SYNC from the phone, and starting from scratch. Wish I had looked at your post
BUT, the big thing I noticed was the change in the screen. The center top and bottom of the screen were extended down and up while the information was larger. Also, the phone now shows email, 911 and the previous battery and strength. I went on line to Ford but did not see any information on this. I just took a photo, hopefully, I have not had a senior moment and started seeing things.
