Hi,
I use a Motorola Razr V3 phone also (with Cingular, but I don't know if that makes any difference). I checked http://www.lexus.com/models/RX/accessories/bluetooth.html and then navigate to the ES-350 site. It has a list of phones, including the Motorola Razr V3 and what features are available.
The Motorola Razr V3 is compatible with the ES-350, but the phone book addresses can only be downloaded one at a time (other Bluetooth phones may let you download all at once). Since I have a small address book, it was no big deal. If you have a large address book, it'll take some time).
I don't know of any other method except one at a time. Sorry I couldn't help further.
