Here's a wierd one,

When the car is cold, or has been sitting for a while, the screen acts as if someone is pushing the left side of the screen (the map scolls to the left) and I can only push the volume buttons. When it warms up, everythings fine. Any ideas? TIA

Something is definitely gone whack there.....

Maybe try to adjust the tilt on it, and see if that helps any... I know mine would rattle at one setting of tilt.... So I left it tilted up one position...

Thanks, I tried that but it didn't help. But I found that when I push up on the center of the bottom row (where the buttons are) everything works fine. I'll probably have to send it to a service center...
