Anyone know if I can fix just the screen or does the entire unit need to be replaced? It's just the annoying line down the middle. I figure you can do it on an iphone so why not a radio.

 

Nope. Can't be fixed. Those look like dead vertical pixel lines. It needs to be replaced. Probably more hassle/cost than it's worth. I'd be tempted to just get a dark pen or fine tip marker and fill it in to make it less obvious, since it doesn’t affect too much of your screen. But I'm **** like that.

 

Can't replace just the screen? I've seen screens on EBay for some of the other Porsche nav systems.
