BlueTooth Wireless Adapter
Motorola's adapter (bought it at Radio Shack, $40) works with my T730 phone (however, it only allows one to key in or voice call a number in the Phone's Phonebook, after which you can then talk through th car's 'phone system), thru /to the Bluetooth connection to the car, but it doesn't allow you to transfer your phone's PhoneBook to the Prius' Phonebook (and, in reading the Prius' manual, the only way to enter PhoneBook info to the Prius is via the transfer of same thru the BlueTooth wireless connection).
I called Motorola, and they said the only way to transfer the Phonebook info was between phones (like when you buy a new phone) using their software and connector cable, which allows one to transfer phoneBook info to one's computer, from where you transfer this info to the new phone--there's no way to do this thru the phone's BlueTooth adapter , however. They said their new V710 model (which costs ~$300) will have an upgrade available, before the holidays, to allow it to transfer its PhoneBook (or contacts as they call it) to the car thru the BlueTooth connection.
I've seen on this forum where an ehurley made a general statement about using the Motorola T720/T730 phones, but I've queried him as to if he was able to transfer the PhoneBook info to the car, but he never replied.

PS: The Motorola people told me there were some new phones coming out soon that Verizon might utilize, but they didn't know what Verizon's plans were.
