My X3 has the legacy MKIV navigation system. Last set of NAV disks I bought were NavTeq dated 2009/10 (don't recall) but they were identical to the 2008 disks that I bought with no updates to the maps. I wrote to NavTeq about the issue; they opened a ticket and closed it about a month later. So I found it a waste of money and actually would say it wasn't right that Navteq updated their disk dates and not the actual maps selling the same map disks for two years without updating them.

I gave my Nav disks to my neighbor a month or so ago; but it was a nice thought and Christmas present from my wife. I have 4 neighbors here with Bimmers. I'm the only one with an X3 (rest have 3, 5, 7 series).
