I upgraded my 4:3 system to a 16:9 and a MK4 about 2 years ago and it has been working well until tonight.

The screen, no matter what mode (radio, computer, nav) rolls in all directions, fast and slow, left/right/diagnal. It still works as I can see it tracking as I go down the highway/street. I kicked the nav DVD out and it still sat there scrolling/rolling with the computer screen up.

Any ideas from the nav-masters out there? Thanks.
