Sync 4 strange issue on just one day.
Phone would not connect, neither wirelessly or with the cable. Everything else appeared to work.
Got home and after leaving the car 20 mins, I put it in reverse, and it said rear camera not available. I don't have a rear camera!!
So next drive cycle everything was fine, and has been for 2 weeks no issues.
This really feels like a software update was done, and made it go a bit funny, and then settled. It was like the new software didn't know what spec of vehicle it was flashed to for a short time
