Just purchased a used 2011 Ford Edge Sport. Love it so far. A few weird issues with the Sync. The other day I got in the car and the screen was blank. Nothing worked. After about 5 minutes, it turned on and a message read, "performing scheduled maintenance" and the Microsoft logo was on the screen. It appeared to be re-booting and after about 2 minutes, the system returned to normal. Does anyone know, is there really a "scheduled maintenance" on these things or does it just say that when it has to re-boot???
