My 2010 F150 Truck came with one and it is the cats meow... This has the foot markers shown on the screen and does beeping when things in view get inside the marker area. You can back right up to the trailer hitch and see the hitch go right over the top of the truck mounter trailer ball. I hit the mark first time everytime now...
The lens is part of the the FORD REAR logo on the tail gate. The only problem I have with mine is when backing up it will flare up on if it picks a light source. Rain drops does a number on the view as well... mounted on the bottom of the LOGO catches all the rain water rolling off the logo..
I guess the newer trucks probably are prewired for these systems.
