Got my issue figured out. I didnt have the reverse signal from the head unit hooked up to the revese signal wire from the gmos04. After I got that wired up it works perfectly

Looking to wire up a camera to my 3300bt, I have power and ground going to the camera(I spliced in to the rear wiper motor as I want to ability to turn the camera one when ever I want), however no matter what polarity I select(battery/ground) the head unit changes to the camera after a few seconds. I tap the screen to turn it off, but it comes right back on. If I turn the camera off, it fixes the problem. Do I need to send a signal wire from the harness to the camera? and if so what color wire do I need to tap?

Having the same issues, So after I wire the power and the ground the the camera, I also have to send the camera signal wire to the power wire for the camera as well?
