I brought my X5 4.4i 05' in for service today and I asked to upgrade to OS. He said you have 2006-2 and the new one costs $250 (I dled the 2007 online, but yet have to burn it). I told him that he misunderstood me and that I wanted the OS upgraded, not the DVD. He didn't understand... Anyways, i will later talk to someone else, but does it actually cost money to upgrade the OS??? Btw, I go to the Open Road BMW in NJ...
