:happy: My 2012 LT has the rear sensors on the bumper that signals with tones of any objects in the path when backing up. I works great and I kind of like it as compared to a camera only setup. My wife's Murano has the factory installed back up camera and it is really nice and she now cannot live without it. Does anyone have experience with an aftermarket unit, preferred a wireless model? My truck has On Star so one that replaces the rear view mirror is out of the question.
