Hi, I am ray from the netherlands. I have a lincoln navigator 2003 since a year. Because there are only a few navigators in the netherlands there is little knowledge about the car. A lot is repaired in the mean time but there is one thing that nobody can find: the display ( in the middle where the logo is on, or the map or the audio ) is running sometimes. sometimes when I ride over a bump, sometimes just like that. The garage says it isnot the wires, because the measured that. But they donot know what is is then. The problem is that when it is running, you cannot use the screen because you cannot see where to push. It is now nearly every ride, so it is very irritating. Perhaps someone of you recognizes this problem ??
