Reversing camera madness.

[tea pot lid]

Hi everybody, I'm completely new to this but having looked around your site, feel with your enthusiasm  and great wisdom someone could help or advise on my troubles.

I have owned the XF for six years and although the car and l have had various disagreements, ( not wanting to start being just one) it still brings a smile to my face when l look at it.

Anyway enough nostalgia, the problem is an old chestnut, intermittent  reversing camera.

The camera and all front and rear sensors stopped working suddenly, having done a little research  l decided to renew the boot tailgate loom using a genuine Jaguar part, l now still have the original problem but have lost the radio as well now.

Could anyone suggest anything  before l have to take it to the moneypit of the dealership.

Any help much appreciated, thanks.
