I tried to see if this works but it doesnt seem to come up. On the nav screen I have it turned on and the manual button is on (not off or lit). I go to back up and I do not see the icon or beeping on the upper screen. Any info would be great before I take it to the dealer.

 

HAHAHAHAHAHAHAHAHAHAHA! It works, LOL. I did a test, guess I didn't back up to a big enough object!
