I would really like to add a backup camera to my 2009 F150. It seems the easiest way to do this would be to use a GPS as the screen. I would prefer to have a wired connection to the camera as opposed to wireless and would really like to use the stock ford camera emblem. Anyone know if this will work?

After watching some youtube vids it looks like most of the GPS systems with backup cameras use a wireless camera that is powered by the reverse lights. It looks like the camera automatically comes on and the screen on the GPS changes to the backup view. Anyone have any experience with these systems?
