I ordered the Ipod interface with my new X5 4.8i.
I am still waiting for delivery though. I'll let you know how it works out. The list price was $499. I talked them down to $350, but on my contract is says $0 so I think they are mistakenly throwing it in!

My first post BTW, nice to be here! This will be my first BMW, upgrading from a 2001 Pathfinder LE. Can't wait!
