2 Minnesota dealers were unable or unwilling to code the rear zoom, even when I showed them how to do it (got the info from the forums). Rear zoom was a must have for me, since I tow heavy trailers that can't be moved by hand onto the hitch. It was a day of rejoicing when I finally got it coded.
You may have better luck with your local dealer, but I doubt it.
