I just installed an aftermarket backup camera system! quite easy i may add!
replaced factory standard auto-dimming rear view mirror with a new Rear view mirror with built in 4.3" lcd screen that you can hardly see when screen is off...(also has another video input if i wanted a, lets say front camera).....
found a flush mount camera and mounted it in the rear between backup sensors. looks pretty good...first camera i had was better, but didnt like the parking lines.
