Query: AM quality sound through your FM car stereo.

I'll make this short and not-so-sweet to the point. If you have a cassette option in your car, use the Sony cassette adapter for MP3 players. If that's not an option, be prepared to be very disappointed with the sound quality of this and similar products. The FM broadcast system to adapt your Zune to your car stereo simply does not work.Either have your car stereo hard wired for a direct connection, or get a car that offers a direct plug in.You have been warned...
