sound quality for me in the car sounds ok. but i've had many people complain that they can't understand me. they say i sound like i'm far away. if i talk loudly and angle my head upward a little so that the microphone by the interior lights gets more of my voice, it is easier for them to hear.
i was able to pair my T-Mobile MDA Windows Mobile phone without any issues. I haven't tried to get the phonebook to sync yet, but I don't think it is possible. that would be nice however if it would.
One other issue i have is that when i place a call, the sound isn't transferred to the car's audio system until the other side has actually answered the phone and said "hello". I never hear them say hello. In fact, I made a call today where the other side hung up before the audio was patched in to the car. When receiving a call, it works fine. I hear the ringing, press answer, and hear all the audio.
overall, i haven't been thrilled with the bluetooth system so far. maybe with some more tinkering it will get better.
