Hi. I have a 1999 Audi A6 Avant with the Symphony radio (tape, cd, and cd changer). For some reason a week or so ago my cd changer and cd do not work. When I push the button for CD or CD Changer nothing happens. Usually if I push CD Changer it would switch from radio to whatever was playing in my changer. Now nothing happens when I hit either button. I have tried pulling the radio out and reseating the harnesses in the back but that didnt do anything. If anyone has any ideas please let me know; I am missing all my books on CD!!

Thank you
