Where Are BMW Maps?

How do I upgrade my BMW's Navigation/Maps?

• I have a 2000 323i with factory navigation (half screen). I just purchased the vehicle and want to update the navigation so it has the latest maps etc... I did some searches and figured I need Navteq CD #3 (for Missouri), or is there another way I should go about upgrading the navigation?! Last question... Would I just pop the CD (not DVD) in the changer and the Nav will recognize it and upgrade?! Thanks in advance for any and all help!!

• Answer:

  Just a few pointers... a) as you very well know already your system works on cd nav disks and not on the newer dvd's b) there are 2 "upgrade" choices, the first is the nav's "operating system" itself and the 2nd is the map (I would leave the os as it is for if the nav is working right now properly then all you need is a newer map version from what you have). Note that a cd map may not be as updated as a dvd map but you have no choice. c) the map cd is inserted into the nav cd computer module/player (not into the cd changer with cassette); it is just a map, like a read-only cd, and the data stays in the cd and does not get installed into the nav computer.
