ok first off i am looking to update Maps on the 2003 M3 is there any easy and inexpensive way to update them. maybe torrents or something of the sort? i am not too sure.

Also what is the point in updating the OS? it currently has 4-1/12 and i am thinking about updating it but am curious about the benefits.


Also the 530i does not have navigation but does have idrive is there any way to add in the navigation?

thanks
louie
