Hey mike1288, I'm looking for a little help. I bought a Smart Rover HU (same as you) and I'm having issues with the back up camera in a manual as well. Unfortunately, my seller, Kevin, has hung me out to dry and refuses to send me the necessary parts to fix this. Could you tell me how that part with the voltage regulator is wired in? I have the voltage regulator, and I just need to know what to do with it. I'm one step above novice, so as much detail as you can spare would be appreciated. I really appreciate any help you can offer. Thanks!
