I am experiencing the problem described. The front screen displays the Land Rover logo and the orange light on the main on/off button flashes. I'd be very keen to understand how I can track down which component is causing the issue or if the MOST fibre optic cable itself has a fault/break...

Did you manage to get to the bottom of this problem as I had the same in my 2007 L322 and now the whole systems has died with just the orange light flashing and the Land Rover logo displayed on the screen.

I have the same problem but without the initial trip to the garage. Did you find out what the problem was and more importantly did you get it fixed?

I have exactly the same problem in my 07 model L322, did you find you manage to identify the problem and more importantly what was the solution?
