PUMPKIN CAR STEREO SUPPORT CENTER

Hello, Long time user of my headunit. Just recently my reverse cam that I have had since 2018 has stopped working. I have checked all connections with a DMM and everything is getting power where it should be. I even bought another cam to make sure the old one was bad. Same problem. I checked the connections to the back of the unit. Both were fine. The RCA was plugged in Reverse Female Plug and the Reverse Wire was also wired into factory harness (reverse wire). When I switch to reverse the screen doesn't even go into reverse screen. Just stays on the home screen. I have tried everything. Is it possible the unit is bad?

have you looked in your settings to see if the camera can or has been switched off?
Mine does weird shit sometimes and forgets steering wheel settings.

put in a relay to power the camera with a more stable power supply and that may work it did for me.
