Mute music when GPS speaks?

Question

My friend has GPS on his laptop, which gives instructions verbally. He also likes to listen to music though the laptop while he is running this program. Is there a way to have the music Mute/Stop/turn down when the GPS orders directions, and then Un-mute/Play/Normal Volume when the GPS stops speaking?

Thanks for your time!

The GPS program is garmin Mobile PC

The music can be played with anything...dosn't matter. WMP, VLC, or another program that may have volume-control capabilities (Kind of like those car's that have dials to automatically adjust the music engine loudness)[[Car Auto-volume]]
