I have the Z1 with ND-BT1

 

Carrier - Verizon

 

Phone name/model - Motorola Adventure V750

 

Transfer Phonbook was a little cumbersome - Once I figured out what I was doing wrong the transfer worked fine. BUT for one name with multiple phone numbers, you end up with the name repeated and you have to go in a relabel each entry i.e. Dave cell or Dave home or Dave work. But it does work.

 

Calling - works well and sounds good.
