rearview camera

I have a 2023 encore gx. My screen is stuck on my rearview camera, even when I’m driving & with the car completely off, in park, etc. Turning off the guide doesn’t help neither. I’ve had this problem a couple times before, always when it’s raining but it’s never lasted longer than 2 minutes...

Need to find reverse wire to hook up reverse control wire on aftermarket double din head unit for camera. 84 Lesabre limited,COLOR AND LOCATION WILL BE APPRECIATED! Hoping someone knows of fuse box or under dash location and color There is a black and a white to the reverse bulb socket...
