Navigation prompts opens music player

[ulfius#AC]

Anyone have the issue when using Google Navigation that when the turn prompts are supposed to happen that the Music Player opens and the prompts aren't heard? This is happening in my car and the car's stereo is connected via bluetooth and I can make/receive phone calls through the car stereo system just fine. I don't even have any songs loaded into the Music Player application. I do have Slacker loaded, but not active. I have a Toyota Camry, so no Ford sync here.
