Newbie X5 owner here. I've read quite a few posts about how daunting it is to pair the Treo 700P or W with BT (I have Windows version). Has anyone discovered a solution for getting the BT system in the car to download the entire contacts/address book from the Treo (not just the picture/favorites)? Or has that not been resolved yet? If not, would it just be best to input favorite numbers directly into the car's BT? Any advice would be appreciated.
