Hello, I got my car (2005 330ci) in February and my navigation has already stopped working completely. The weird thing is that the screen still shows the exact street and city I am in but if I try to get directions the screens says "disc error" I am bringing it in for service in 3 weeks. I have tried removing the CD and putting it back in but that doesnt work. BMW said that they can not send me a new CD, which I think would be much easier than wasting time going to the service depot if in case the CD is the problem. Has anyone else experienced this problem? Thanks!
