That post is for a 2004 X5. The cradle for those models includes a pairing button for the Bluetooth. Flexstar's X5 is a 2005, so it needs the cradle w/o the pairing button. I think Flexstar has idetified the correct part numbers, but I am waiting for him to receive the parts and confirm that everything works before I order the parts for my '05.

There has been way too much confusion about which parts are required for which vehicles. BMW, on their Bluetooth microsite, really needs to publish a chart or table showing the proper configuration and part numbers for each vehicle and phone model. BMW has not made this very easy for us!
