Nope, this is not possible with the Verizon V710. Verizon deactivated the Bluetooth file transfer functions of their bluetooth phones so that people have to use their pay per use services to transfer pictures and files. Its a totally underhanded business practice but they did it, currently Lexus, BMW, and Acura are suing them and there is a class action lawsuit in CA pending. My fiance and I have a Prius with the Bluetooth and I paid $700 for two V710s and Verizon service and we got screwed because they don't work. I'm going to pay the $350 cancellation fee next month and go back to Cingular.
Without the bluetooth file transfer you cannot make calls while moving from the car because the only way to enter phone numbers is by transferring them from the phone. You can still dial calls and if you make calls from the phone they will work through the car's system, but you wont be able to set up the car's phonebook with the V710 or any bluetooth phone from Verizon or Sprint.
The phone also doesn't reliably sync with the car either, somnetimes it just won't transfer calls through. Its not only supposed to mute the radio its supposed to ring, and its supposed to show battery and signal stregnth on the screen, niether of which works because of Verizon crippling the bluetooth on the phone.
So, no phonebook transfer, no ring, and no signal stregnth. All you can do is use a bluetooth earpiece.
Beware that Sprint does this too, their LG Bluetooth phone doesn't support file transfers either. SO if you want a Bluetooth phone to work with the Lexus it has to be from Cingular or T Mobile because they're the only nationwide carriers that don't cripple their bluetooth phones to cheat their customers.
