UPDATE [21st Nov 2008] – Apple have released iPhone 2.2 software update which appears to fix all known issues with BMW bluetooth and iPhones. If you had no contacts syncing or bluetooth kept dropping the connection every 20 or 30 seconds then update to 2.2 and you should find it’s all fixed.
Looks like we’ve found a fix for this that involves creating a large number of fake contacts on your iPhone. Mine started working when I sync’d with my Exchange server and 2500 new contacts appeared on my iPhone and at the time of writing this 3 out of 3 people who tried the fix have reported back with success.

UPDATE (18th August 2008): ****FIXED*********NOT FIXED***** Apple have just released iPhone 2.02 update and I’m currently downloading it. Hopeful that this update will finally fix all the iDrive address book issues, watch this space…..I’ve just got back from testing 2.02 with my iDrive and finally, it’s working again! (iPhone 2.02 fixes BMW iDrive contact syncing)Sorry guys and girls, it looks like a was a little premature on this one. My contacts DID all show up on the iDrive screen and I scrolled through, jumped from A-N-W-etc and I came in to get the camera for a few shots for this article. When I went back out, my iPhone paired but after a long wait screen there were NO contacts shown! I removed both pairings, powered off the car and the iPhone and tried again but still nothing. I then updated my friends brand new 3G to 2.02 and tried syncing that (which has never been seen by the car before) and it paired but still no contact sync.
