My rear camera works fine but I was thinking of the possibility of having a switch made so that the camera can stay "on" without going into reverse gear mode. It would help during driving as the rear spare wheel arch is a problem.
I also ran into a Kenwood 2 DIN unit model DDX8037 that has an input for a rear camera and a 6.5" display. Was considering to replace the stock Clarion unit with the Kenwood if I hit the lottery.
