Has anyone found a good screen protector for the 3.0 PCM? I m looking around on the web and havent found anything yet except for those cut yourself to size ones. I figure my wife's iphone has a screen protector, her car navi might as well too.

 

The reason they dont exist is because there is no need for one. It would take some doing to be in a position where the screen could be scratched.

Also, remember the screen is anti-glare with a nice matt finish, adding a protector would make it difficult to see in bright daylight.
