Thanks for the info. I agree, it sounds like a phone problem that Motorola/Verizdum would have to fix. I don't like renaming my entries either. I sync my phone with the address book on my Mac, so it would screw everything up.

In the meanwhile, the voice dialing works well but I wish it was simpler. Having to make three voice commands to dial a number is at least one, maybe two too many. Why can't I just say "Call (name)" and then hear the car say "Calling (name)" and pause two seconds. If it mistook me for a different name, then I would just hang up before the call went through.
