I am heading to Munich to pick-up my X3, and my plan is to drive from Munich to Prague then to Hamburg via Berlin I am not to concern with the drive in Germany since I have done this drive couple times in the past, but I have never been in Czech Republic. I'd been searching for NAV disk for this country but I have not been able to find out which is the right one to get.

. Does anyone in this forum knows how to get the right one, the one that works in my new Bimmer. Thanks for your attention to this.
