How can you connect an ipod to a 2004 Audi A6?

I have a tape player in my Audi, however i am not going to use it. Is there a place where i can connect my ipod so it plays my ipod music? If not, what can i do to make this possible?|||You can do that, or if you want better fidelity, you can get an adapter from enfig.com, that plugs directly into the CD changer cable.|||Convenient stores like CVS and Walgreens sell Auxiliary cables attached to cassette tapes, for around 15 bucks. I used one for like 3 years in high school.



Here is a pic of the closest thing to what i used.

Throw the tape into the radio and plug the AUX into your iPod..good to go!
