Good info! Thanks everyone. I guess I'll skip the PPC and go for the Treo.

Also... I've heard from some people that the phone only VR module comes with the Assist/Bluetooth module and that you only need to add another VR module for NAV... and I have heard that the phone only VR module doesn't actually come with the car. Anyone know which is true and if it is not already in the car how much the phone only VR module is? (I don't have NAV)
