Yes, the part # is correct, I grabbed it straight off of the DVD. The disk you show is for the previous generation iDrive based NAV (CCC). The two NAV systems are not compatible with each other and each requires it's own maps disk. I happen to have both disks at home, one for the Z4 and one for our 2009 5er wagon.
