HI All.

My 2008 58 XF has started messing about.

When I select Reverse, The Sat Nav comes up instead of the camera!
Sometimes the camera works fine. Sometimes I get a black screen (Could be any colour).
Sometimes it looks like a Spectrum ZX loading!

I'm guessing the sat nav unit controls the camera? Is this going to be a loose connection or a replacement unit?

All suggestions welcome and appreciated.

Thanks.
