Yes, of course.  You'd have to reverse engineer the control protocol
and build a circuit or something to do it.

Fortunately, Audi already has a solution for you, if you have a relatively
deep wallet (about $650 street price).  It's called the PhatNoise PhatBox
digital audio player.  It goes in place of your CD changer, and connects
to your head unit the same way the changer would.  The head unit controls
the player.  The PhatBox has a removable hard disk cartridge (comes with
a 20GB unit, you can get more or get larger capacities), and it stores
MP3 files as well as other formats for playback.  It also comes with
a cradle and cable that allows you to connect the removable disk to
your PC, so you can rip CDs and download music onto the disk at home,
then plug the disk into the car.  You could conceivably store your
entire CD collection on the disk, so it makes a CD changer rather
redundant.  If you do want to play CDs, there is always the in-dash player.

People have also adapted the Apple iPod to Audi's sound system (with some
wiring work and an adapter into the CD changer wiring).  Since the iPod
is small, it can sit in the cabin (like in your armrest bin), and be
operated by hand.  Here is an article on how to do this:


Other small, handheld portable MP3 players can be similarly connected.
