There are few IBus adaptors which allow you to use steering wheel buttons and retrieve some info about engine car etc. There is a KBus too but i don't know too much about it yet.
By the way there are 3 differently methods to play your audi thru your e39 headunit.
-casette player: put a empty casette in your casette player (You have to remove the tape to avoid noise) . Remove the audio cable. Make a simple adaptor between the car and pc with two cables and a normal small audio jack (an old headphone or pcspeakers). Plug audio cable in your audio source or pc. When you choose casette you hear your pc.
-radio: plug and easy fm transmittor in your car, save it on your radio, when you choose fm and push channel 1 you hear your pc.
-cd changer: this one is best and most common one i guess. And this is nicely explained above.0l33l
