After 18 mos of no BT (Treo 700W) my system is complete. I've spent about an hour on on the phone through the Z1 and no issues, & noone could tell that I wasn't using the phone directly.
I can't figure out how to transfer the contacts list either, but that's a pretty minor problem in my eyes, since I've never even had BT before, dispite my having all the req'd equipment.
If anyone has questions, lemmie know!
