I went to a local Verizon store. They took one of their Treo 650's out to my car (2005 X5) and tried to get it to pair. No luck. The phone kept turning off, or some such. I have tried, thus far unsuccessfully, to find someone at Verizon or Palm to tell me if/when a patch for the Verizon Treo will be out. If anyone has info on that, it would be greatly appreciated. Oh...and a correction to my earlier post. I have the Motorola v551 (not 661!!!) from Congular, and that works fine, altho just recently it has occasionally failed to pair when I get in the car. Then I have to remove the phone battery and re-install it to restore pairing.
