I've got a weird backup camera issue with my 8200. Everything was professionally installed, and generally works well, but my backup camera only works intermittently. When I put the vehicle into reverse, the head unit will change to the reverse camera view, but about 50% of the time, it'll be a blank screen, and 50% of the time it'll be the camera feed. Sometimes while I'm backing up, the screen will either switch from the feed to a blank screen, or from a blank screen back to the feed. Other times, it'll stay blank the entire time I'm backing up, or show the feed the entire time I'm backing up. The troubleshooting I've done so far is: Disabling and removing the front camera (in case that was somehow interfering) Updating the unit's firmware Checking the wiring from the rear camera to the headunit for loose connections Anything else I should try?
