Interesting, but seems more complicated and less practical than just having (a) an iPod interface, and/or (b) a USB port that accepts flash drives filled with music.
Fantastic German made Music Server for my Car
I was shocked the other day to find that my car has a music server as part of the audio system. Who knew? I was clearly clueless. I'm sure a lot of new cars have this feature but I accidentily discovered it the other day when I put in an Andrea Bocelli cd for my mother-in-law (it was going to be a long drive with the family) and there was a message "do you want to record cd". Of course I said yes and I have to admit it's very cool, convenient and sounds pretty damn good. I have loaded the hard drive up with lots of varied and fun music for long drives.
