While reversing, the aœMMI systema which displays information on the central display screen, such as the backup camera, will crash and reboot. This will also occur while driving normally. If this happens while reversing, the car will then warn me that the backup camera safety feature is inoperable. This issues was NOT solved by a deal software update and requires a $4000 repair charge to resolve. Backing up without the camera operable at random times does not seem safe.
