I bought this one off Amazon. It attaches over the rear-view mirror and that's the display screen.

Pictures of the finished product(s). Front dash cam. Backup camera.

The dash cam itself just goes on over the rear-view mirror. It plugs into the cigarette lighter, so I did have to run wires and tuck them in the weatherstripping all around the car. The back-up camera I attached right above my license plate, came with all the screws etc. There was a hole that was plugged up that is where I assume the back-up cam wire goes for the up models. Drilled through that for the back-up camera's cord.

I did have to pop off the interior paneling on the back of the hatchback to access that area, and that's where I connected the reverse light indicator positive lead to my backup camera. Should've taken a picture of that, still might. It'd be easier for explanation purposes.
