I just an audi a4 and it does not have a disc changer. I looked on ebay and they have disc changers for 96 audi a4s. I was wondering if all 96 a4s are capable of having a factory changer installed? forgive me for my ignorance as I am sure I will have tons of questions about my new sedan. I sold my land rover discovery for this, so this is a completely new thing. Thanks for your help guys.
