Hi all
The reversing guidelines have disappeared, the camera comes on when reverse is selected and the reversing lights all work as expected. Anyone any ideas? 2011 TDV8 4.4 Vogue SE in Galway Green with Black leather

I had no lines and no beeps but had the reverse camera. Swapped the parking control module think it was 170GBP. That brought the reversing lines back. To get the beeps back it was the speaker at the back of the car. Current

I've just experienced the same problem - lost the lines on the screen, lost the beeps. I pulled the parking control module out and found it was full of water!

Its at the back of the car in the boot on the left hand side. Looks like this. Current

@LowB:

Cheap fix:

Paint a pair of lines on the inside of the rear screen, and reverse using the interior mirror?

 “If it ain’t broke, don’t fix it” -where’s the fun in that?
