^ I think your getting the map DVD mixed up with a software upgrade. New map DVD's are released every so often from Navteq, I want to say twice a year, but I'm not for certain. Software upgrades are as needed from BMW, or whomever handles that for BMW if you want to be technical.

Its my understanding, however, that your setup can technically be "upgraded" its just something the dealership has to do. And they will only do it if your really having trouble with your current version.

I think the poster above you is basically saying the link must be to an iDrive map DVD because it didn't work in his e46 MKIV system as a map DVD.

I could be wrong though, it wouldnt be the first time...
