Turning on the camera for reverse only is a simple matter that only requires a relay. I have mine turn on when I back up OR change lanes. I can also turn it om manually as necessary. I also have front camera that is manually switched but will be connected to a DVR for next Moab - probably put another on the roof as I don't want the camcorder up there again!

Small cameras I offer require NO cutting of the rear crescent, are waterproof and easily adjustable up or down once installed. Rizzo, can you shoot a picture of your mirror in the daylight? I need to call on the one I found at SEMA but it cost more than what you paid!
