A few weeks ago I lost 1/2 the screen (E70) and it shifted left when it came out of the back-up camera. Interestingly the only problem was that I could only choose the radio stations that were on the screen which I found really confusing until it came to me that the screen is not displaying the radio but controlling it, "what you see is what you get" programming because they were thinking ahead to touch screens.
It wasn't serious but I felt a bit helpless. Hope that doesn't happen again! (which isn't a good thing in itself)
