The Blackberry Tour evidently has a software issue with bluetooth. When the I use the bluetooth in my car, it is very hard for people to hear me. It sounds like you are standing far away from the microphone. When I use my Jawbone bluetooth, there is not as much of a problem as the car bluetooth. This was never an issue with any of the previous Blackberrys that I have owned. I had Verizon verify the problem and they then connected me to Blackberry. When I was finally connected to a senior Blackberry rep, they admitted that there is a software problem with the Tour and they were working on resolving it. There is no estimated time to resolve the problem.
