Newbie Needs Help with Navi screen

My 2008 BMW X3 Navigation screen died last week. The GPS still functions, As it was still giving me commands, and my radio plays, just no display on the screen. Anyone have similar problems or know a good way to diagnose the problem I am having.
Thanks

The screen images are generated by the nav computer. Is the backlight lit on the display, and the screen motor working - indicating the power is OK? The nav drive is used in E46, E39, Z4, E53 and is a MK4. ?You could google for then same issue on those vehicles. You may have a dead video card due to water ingress.

Thanks I will google seach that. The screen is not blacklight at all. The motor for the Navigation screen is not working, It is stuck in the up position. Will not close manually by button or automatically when I shut the car off.

Fuse are all good. Anyone know if there is an inline fuse for the screen?

No there is not. It's time to go step-by-step from the basics. Check the power and GND with a multimeter. Schematics are here. http://www.bmw-planet.com/diagrams/

Update to this thread. It turned out to be the gears were stripped in the navi screen. Replaced navi screen and motor with a used one, and everything is perfect.
