It just turns the music down to make sure you hear the warning chime. It's only annoying when you get a lot of false positives.
My experience (so far) is that you will get false positives after overtaking traffic and moving in front of them at a safe distance, but one that's still a little too close for the system's comfort (hey - in urban traffic you don't get long gaps).
Another false positive comes when you are in the outside lane of a multi-lane turn. If you put your blinker on and turn, and there is someone inside of you also turning, the system doesn't know that the insider must turn and will chime.
Lastly, I've had a couple of completely mysterious "BRAKE" warnings from the ACC when there's nothing in front of me. I'm trying to figure those out and will report more if I can pick up a common thread.
