Volkswagen is offering the PhatNoise mp3 system for their cars. It uses 20GB cartridges which you load with mp3s from your computer and then insert into the trunk-mounted player. It\’s a very well integrated system: the player mounts in the CD changer bracket and it\’s all controlled by the stock headunit. This would be perfect for my Golf except I got rid of the headunit long ago. It\’s also rather expensive ($795 from the DriverGear catalog). I have my iPod hooked up to my car stereo through an auxiliary input cable and it works fine, plus I can use the iPod anywhere.
