so not sure if this helps..... for the head unit to recognize your going into reverse when you go in reverse and give signal to turn camera on and show you video from camera you need to connect that wire for reverse signal to the wire coming from the car.  if you have a certain module like i have for my buick it will be labeled if not you must do some research to find the wire on your car that will give voltage when in reverse.


so you need power and ground for camera and connect rca to camera rca on radio

thats all camera needs to be connected to.

then if you go to settings forgot actual steps but there is like a diagnostic screen that will show you your gps signal speed sensor signal reverse signal.

go to that put car in reverse and make sure the reverse signal changes otherwise its not connected right.
