Hello.
I haven't got any pictures of the display. Will get one tomorrow and post it ���� Quality isn't mega good, but clear enough to see what you need too. (Take into account how much this costs in comparison to the vw kit)
You can also buy whatever camera you want. Mine was £12. You can buy a better quality one.
As far as the wires go. You install the connects2 lead behind the stereo and it has a video in which comes from the camera. Only other wires you need are a live (when in reverse) and a ground. The connects2 lead has a wire coming off it which goes live when You go into reverse (it works with the canbus system, so no tapping into reverse light wires) so you tap the live from the camera into that one. Then just ground it out on some metal.
If you don't have led number plate lights then you could order this camera, which saves screwing the camera onto the bumper and makes it a bit more of a clean install. Only downside is the camera isn't centred. Mine isn't centred and isn't bothering me too much. I only use the display to see how far I am from something behind me and to see what's there, rather if I'm straight or not.
Number plate camera.
