I've been thinking about this as I may need a new screen sometime soon. I would prefer oem as they are better, and don't want any problems with a copy.
I have heard some insurance companies will not supply oem because of the extra cost. But here's a thought, if the insurance company will only replace with a non standard screen, does this then mean they could put your insurance premium up because your car is now non standard because it has a "modification" ie an after market screen.
If they don't, its kind of double standards isn't it, and shows how much of a con insurance is.
