Hi all I have just retrofitted a reversing camera to my b7 variant however I am have calibration issues as I have now lost my base value s and wondered if anyone knows what they should be
I had this on my CC several years ago. Calibration would always fail. What I had to do was place chairs around the calibration board with dark blankets over them to put the board in shadow. Calibration worked first time after this.
My presumption was that the camera was seeing reflections on the board from the sun which it didn't like.
I had the same trouble calibrating it on my RSQ3. Try moving the calibration board closer to the rear axle. The value on ElsaWin said 1.47 to 1.90 metres, but I could only get it to calibrate if I reduced it to about 1.43m. I also found I had to lift the calibration board up at the back by about 100mm.

I think you'll find that the 1.47-1.90m dimension applies to most models. It is certainly the same for a Q3 and A4.
When I said I lifted the back of the board by 100mm, I meant that I tilted it up at the back - not raised the whole thing up. If you look at the photos in the link I posted you will see what I mean.
I used the link I have already posted and stuck A4 sheets together, worked first time. I was pretty precise with the measuring etc from the wheels.
