Kind of a newbie question, but I just got my '04 X5 with Nav system. It has a DVD based nav system and the dealer gave me a DVD to go with it.

My question is, is there any way to get the cool 3D looking nav software on my system? I think mine is running version 4 1/2 or something like that (I will have to check again next time I am in the car).

I assume my DVD is new, but is there a newer version of the software for the Dealer to upload to my Nav or is what I have all that is out there?

Thanks so much!
