I am trying to connect a back up camera to my xo1931 stereo. The pos/neg is connected to pos/neg on the battery (testing before I drill holes)the video out is connected to video in on the unit. I have touched the "reverse" wire to hot and tried it without but nothing on the stereo. The only mode option is aux and radio. Help!
