Of course, just a few years from now CD players in cars will be a thing of the past. I'm amazed cars don't come with a music hard drive built into the car. You could take your iPod, copy everything from it over to the car and go. It could be a removable drive, thereby making it easy to have a backup unit available in case of a failure. Pioneer used to make a head unit with a hard drive built in, but it was ridiculously expensive at the time - over $1000, as I remember.
