Need help with my back up camera. When I put the vehicle in reverse the camera doesn't come on it stays on the screen it was on which most of the time is on radio. I know the camera works because i had install a module to allow me to activate the camera when I'm in drive. I use this module when i am hauling an open trailer. I check the forum on back up camera issues where people on the forum asked to check the navigation settings to see if the option for back up camera was off it is on i checked. Also another forum asked if when in reverse are the reverse lights coming on, yes they do come on in reverse. What suggestions can you guys give me to try.
