My van is devoid of windows in the cargo area so I'm totally dependent on the back up camera while maneuvering out of parking spots. The camera angle provides a very low angle of view which is great for hooking up a trailer but limits the distance seen to about 20 ft so I can't see cars coming in my direction nor anything else in the distance. Is the camera adjustable? I noticed there is a little hole in the bottom rear of the camera assembly that I hope may be the answer. Just thought I'd reach out to see if anyone has experience with this before I start messing around.
