Local dealer and NavTech only supply the 2001 version of the Nav CD for the 2000 S. Is there any after market provider for 2006 or 2007 CD updates? Maybe we can use the 530 BMW CD from the next door neighbor? I hope we are not the only ones who would like to update from 2001 to current. If there are no updatesfor the $1,800 paid then our Navfeatureis nowobsolete.
