After reading this thread I played with my backup camera. This is a 17' TC XLT cargo van with barn doors, Curt hitch and wiring and it has SYNC. Right away I discovered while in reverse if I push the third button over from the L like I was selecting something on the radio screen the camera picture magnifies. If I remember correctly it deletes the tracking lines and has more of a downward angle picture. It works really well for backing up to a trailer, in fact, it is very accurate! Oddly, to go back to the normal view I push the same button not the second button that lines up with the - and it's default is always the normal view.
