We have designed and manufactured several products that allow you to add an iPod adapter or an Auxiliary AUX input to your factory Audi radio while not disabling your factory installed XM or Sirius Satellite radio module. We worked with the Audi Dealership in Manhattan for several months to engineer the products below. (Just wanted to mention them since they are a great group of people that went out of their way to work with me on this)
