give it a while it'll be on the net for free somewhere i'm sure. during the life of my E92 I started out with the factory shipped "official" 07 disc...ended up with the 2010 disc working fine and in-between had 2008/2009 discs all of which came *cough* via t'internet and a DVD burner
i steadfastly refused to pay BMW the 180 GBP they wanted back then for a DVD that had probably 10 new roads in it
