Hi there,

I just upgraded my 06 x5 4.4 North America DVD map from 2006 to 2009.1. For my curiosity, I duplicate the 2009.1 North America map with Alcohol Soft trial version download. And it's working beautifully with single DVD disc. I could not tell I am using my duplicated disc. It's 100% accurate. Now I have many backup 2009.1 DVD discs to use. I get this tips from X5/Navigation group from x5 forum. Thanks,
