I am using my Cingular BlackBerry 7100g via Bluetooth with general success. The only thing I can't figure out is how to transfer the phonebook to the Nav. Can this be done?
No, there is no software on the 7100 which will transfer phone entries. You can transfer phone entries from a laptop with a Bluetooth adapter if you have a Bluetooth phone, however. See here. I would try my directions which are somewhere in the comments.
