We installed our wired back-up camera 3 years ago when we went fulltime, and never had a bit of trouble with it.
Our dog occasionally has knocked the monitor around, jumping on and off the dash, but still no problems.
Suddenly, the image is now upside down. I checked the box/manifold under the dash that all the wires plug into, but it only has a control for "mirror image" vs regular image.
I actually was able to take the monitor off the stand and prop it upside down to use it, but that's not a long term solution (not unless I use duct tape
Any ideas why it did it and how this thing can be fixed?
