The bluetooth is supposed to disconnect from your cell phone, and then you will see the transfer screen on your Z1.
After you have the Z1 in this mode, go to your contacts menu, and select a contact you wanna xfer, and then hit whatever key will bring up a context menu for your contact. In that menu, there is probably an option to send or "transfer", like my nextel, and you'll probably have to select the target device, your Z1, pick it's Bluetooth device name, and it should transfer.
There is no apparent way to wholesale transfer your list to the Z1 at one time, you have to go thru your contacts and pick the ones, and send each one individually.
This will save time, but in my case, every contact went into the Z1 fine, but either my export, or the Z1's import function interprets the contact name as a proper name and switches the supposed first and last name, e.g. Home Depot in your cell phone will become "Depot Home". Wish there was a way around that one. Duh. and the Z1 only types in upper-case, slightly annoying, but it still ROX.
Took me some fartin' around and some RTFM... Hope this helps.
And RTFM (read the f****n'manual(s))
