VW does mp3

VW just sent me a post card annoucing their new "PhatNoise Digital Car Audio System" is available at dealers. Looks like an interesting system that acts like a CD changer you store in the trunk with "cartridges" that must be hot swappable hard drives. The prices look pretty steep for just 20Gb of music, and there's not much in the way of details. I wonder if it plays plain old MP3s or if it requires a DRM-laden format.

I also wonder how they kept this under the radar. I've never heard of these (unfortunately named) "Phatnoise" systems until today.
