[&o] I bought an 03' A4 3.0. I want to hook my iPod directly to the "symphony" radio. Does anyone know where I can get the harness. And how hard is it to install?

 

You need to purchase an adapter, either directly from Audi, or from Dice. It takes place of your CD changer & you use the cd changer controls for the iPod.

It comes with all the wires to hook up to the factory harness.

 

Icelink connect through the CD changer.
