yeah this unit remembers the location as well, it automatically folds back down whenever you shut the car off, it's quite nice. I usually prefer stationary double-din screens but for a fold out this one has been pretty nice.
I don't think you'd need a camera specially built for this unit. really any camera that outputs a composite video feed should work. you could actually use a camcorder if you really wanted to. The monitor has a wire that you hook up to the shifter to automatically switch to the camera when you put it in reverse. It's literally just a video input like what you'd find on the back of your TV or VCR so you can hook up just about anything.
cameras range in quality quite a bit though and being a backup camera I think the two most important things for me would be night vision as well as how well the camera holds up to the elements, particularly the cold since I'm up in the North East and we get some cold winters up here.
though based on what some others have said even the cheap ebay cameras seem to work pretty well![]()
