Those cheap back up cameras are good for about 4 years if the vehicle sits out in the weather. The camera lens starts getting foggy and the image gets blurry. Still pretty cheap back up views. Might want to pick up a second one to have on hand as a replacement when needed. You get pretty used to them, and I only use mine for backing up.
I mounted the view screen up by my sun visors (with a home made screw on bracket) and ran the wires along the windshield pillar. The suction cup thing is worthless. I don't even have an E body, they work on lost of stuff.
I have a more expensive one (Furrion) on my camper and the lens got all blurry, I had nothing to loose so I wet sanded my camera lens with (I think it was ) 600 grit and now it’s clear again. Just a fine polish was all it needed to remove UV or whatever was making it cloudy. Sounds scary but it worked…..found that info online somewhere.
