Hello all

I wonder if anyone can give me some advice?

I have a 2007 RRS L320 with the Denso touchscreen. The main menu shows options for navigation, 4x4 info and settings and I can select everything in these menus and the screen displays all information and allows me to make any selection, until I get to the sat nav map screen. This just displays as blue and shows the vehicle as a yellow triangle.

I’ve tried removing and cleaning the disc, but this changes nothing. Should a fix be as simple as buying a DVD cleaning disc, or could it be something else?

Any advice gratefully received.

Thank you.

As far as I remember, a blue screen means there is no video feed from the satnav computer to the display (what you see on the display is actually taken from the video output of the satnav computer). Can be caused by the computer not starting up properly. Some map discs contain a firmware update to the computer, perhaps loading such disc and booting up the computer would update the firmware and bring it back to life? 2011 update had it, if my memory serves. Regards etc.,

Hi

Thank you for the response, how would I carry out the update please?

I did it ages ago but I believe it was fairly simple: if you happen to find a relatively (2011!!!) new disc (you can check if it contains the firmware update by putting it in your PC and looking for a file named "loading.kwi" on the disc), just pop it into the satnav computer and turn the ignition on. I don't have any way to check it but perhaps one of the chaps with a prefacelift will confirm this. Regards etc.,

I’ll see if I can find a suitable disc and give it a try. Thank you for your help 👍
