I was thinking about projects I can't afford the other day and was wondering if one could rewire the side-view mirror adjustment toggle so that the switch's middle position wasn't "off", but rather "rear view camera". Then, you could adjust the rear view camera with the same factory toggle we do our mirrors with. I too was thinking to do the actual movement with a mirror-adjustment motor. Seemed like a neat and tidy install, but I don't know if it can be done. Just an idea to throw into this brainstorm

Good luck - let us know how the project turns out
