Reverse camera fitting

[A3jack]

Yet another question sorry lads! I've upgraded to a double din from single din in my a4 b7 2005 avant, I'm fitting a reverse camera, it's a number plate holder with the camera built in, I have a red and black wire which I'm guessing the red goes to the reverse light live! And the black the ground, and one wire with a yellow connector which I'm guessing a run to my screen and that's it sorted? Or am I missing something lol! Any tips off people who have done this ? Thank you Jack

Hi Jack, I imagine it depends what screen you have? Is it a separate screen for the camera or is it the screen on your double din audio equipment? Probably a silly question but what do the fitting instructions (assuming you have them) say?
