I have a 2004 X4 with nav and ive been using the original DVD it came with. My question is how often does BMW update them DVDs and where can i get one.
The reason why i ask is because it seems that as my x5 gets older its not giving me directions as good as it used to. I think it needs updated info for maps and stuff.

Also how much do they cost and can you get them anywhere besides the dealer.
