Mirror I disabled. The video input is missing to it. I know WHERE it is in radio as I have the manual for the car but not entirely sure where it is on that car without a lot more time and prodding. If you look closely in the rear camera you will see two systems there. The camera controller on the 2008 is still showing under the 14 one that the radio provides. I could kill the lines in set up but it breaks other things doing so.
I widened the radio lines as they were off center and too narrow.
