I just picked up my 07 X3 in Italy (US Spec, though Military Sales) and will be staying here with it for a few more months. I'm having a hard time figuring out which DVD or CD to use for the Nav.

The dealer gave me a DVD from a 525, but it will not recognize it in my car. As I search the forums, I think I understand that there are two different ones, one for iDrive and one for others. But on BMW's European Delivery information page, it references that there is one for the 3, 5, and 6 series and another for the 7 series. There is no mention of the X3 at all there.

So what do I need? I want maps for all of Europe, but in English. I suppose I'm going to need to refinance to guy it too, right?
