back up camera

Hello, I'm curious if you've encountered a software glitch or if there is an issue with the connection to the head unit. Also, if the head unit doesn't know the transmission is in reverse, there is no way for it to turn on the camera, so you may have a data line error from the PCM/TCM to the head unit (nav unit). You need to get it connected to a scanner that can verify the data lines to and from the head unit. This could be difficult to figure out.
