Let us know what you get, because the press release indicated that the new interface would not be available on the X5:

"BMW today announced the debut of a new iPod interface that will enable tighter integration of the iPod for the newest generation of BMW models, according Leftlane News. The new system provides direct access to playlists, artists, albums, podcasts, and genre via the car's interface. The new BMW Interface for iPod will be available for owners of the new BMW 3-, 5-, 6-, and 7-Series. It will also be available for the new M5 Sedan and M6 Coupe. The new Interface is compatible with all iPods with a dock connector, including the iPod nano and the fifth generation iPod. The BMW iPod Interfaces integrate the iPod through a direct connection in the glovebox. The company said that the original BMW iPod Adapter will continue to be available for 2002 and later BMW models: X3, X5, Z4, and previous generation 3 Series."
