You will be able to pair up 7100 series. Unfortunatelly, due to RIM/BlackBerry security 'features' there is no way to transfer the phone book.
Paragraph below is from the BB security document at:
http://www.blackberry.com/knowledgec...27186&vernum=1
"* BlackBerry device users must type a passkey to complete initial
connections with any Bluetooth wireless technology enabled device, and
they must manually accept all subsequent connections. Only by setting
the paired device to the status of trusted on BlackBerry can users
bypass the manual acceptance step. This capability is not enabled by
default on the BlackBerry.
* BlackBerry device users cannot compose or send SMS messages remotely
using Bluetooth technology.
* BlackBerry device users cannot access the address book remotely using
Bluetooth technology.
* BlackBerry device users cannot initiate phone calls (other than a
basic redial) using Bluetooth technology. "
The last two defeat the purpose of BT/Handsfree operation (no phone book and no voice activation).

People from US are reporting the new BlackBerry 8700 works perfectly with the Bluetooth System of the BMW...including the address book. Not sure about Lexus.
Good sound quality. That's needed cause the BB 7290 sound quality is not that good.
I also read reports that BB OS 4.1 (not released yet) will be able to transfer the phonebook to the car.
Hope this helps....
