Here at Enfig Car Stereo we answer the same questions every day so I figured that if I made this guide it would clarify most of the questions and let us get back onto the forums. We specialize in Volkswagen & Audi. We also carry all the relevant iPod interfaces on the market and have been selling Auxiliary AUX interfaces for over 10 years since they were just used for people who wanted a direct audio input for their in-car TV’s. Everything on this page is for sale on our website EnfigCarStereo.com or you can click on the image of the item for a direct link to the item. PLEASE READ THIS ENTIRE PAGE BEFORE CALLING US WITH QUESTIONS. It will help you make the best decision as to what interface you need and help keep us from answering repetitive questions. But if you do have questions after reading this please feel free to call us. We will be more than happy to speak to you.
Lets start with the car.
A4 2007 2008
What type of audio system you have does not matter with the 2007 & 2008 A4. There are two different radios in these cars. In dash 6 disc radio and the RNS-E Navigation radio (us market). All of these radios have an external CD changer port that is tricked into thinking that there is an external CD changer attached so that the audio port is activated and opened to allow the transfer of audio from your iPod to your radio. NONE OF THESE INTERFACES WILL DISABLE YOUR IN DASH CD CHANGER OR CD PLAYER.

Glove box CD changer removal

You can use the radio removal keys above to take out the CD changer.
Connection Locations
There are 2 places to connect your interface. To the CD changer port behind the radio or to the black CD changer port in the glove box. All cars have the connection behind the radio. Usually only the cars with factory installed navigation radios have the connection in the glove box because all cars equipped with a navigation radio also come equipped with a CD changer in that location. If you do not have a CD changer in the glove box it doesn’t hurt to check but unless someone swapped the navigation radio out of your car before you purchased it you will not have the black connection in the glove box. A very small amount of cars with the in dash CD changer came with what is called iPod prep and also have the connection in the glove box.
Factory Satellite Radio
If you have factory XM or Sirius satellite radio it will be plugged into the CD changer port. If you don’t plan on using the XM or Sirius satellite radio you can just unplug it and disable it. If you plan on using the factory XM or Sirius satellite radio there are 2 options. All cars can use the Enfig Audi Sat Pass 2 http://enfigcarstereo.com/shopsite_sc/store/html/ENFIG_AUDI_SAT_PASS_2.html. The Enfig Audi Sat Pass 2 connects behind the radio on one end and connects to the satellite tuner in the trunk on the other end. If you happen to have the glove box CD changer connection you can use the Enfig Audi Sat Pass 3 http://enfigcarstereo.com/shopsite_sc/store/html/ENFIG_AUDI_SAT_PASS_3.html. This harness was designed to connect behind the radio on one end and to the CD changer connection in the glove box on the other end. They both do the same job but obviously the Enfig Audi Sat Pass 3 will make the installation easier if you have the glove box CD changer connection.
Ipod
If you have an iPod there are interfaces that will give you an iPod specific input as well as a universal AUX Auxiliary input. For more information on these devices click on the following link. http://enfig.wordpress.com/2010/02/03/audi-ipod-guide-a4-2007-2008/
While there are many different manufacturers that do AUX auxiliary interfaces there are only a few we sell and recommend.
BlitzSafe
It works through the external CD changer port. The radio displays disc 1 track 99. The Satellite splitter is built into the behind the radio interface. Notes:On the later radio software if you press track up or track down on the radio or steering wheel controls the radio will lock up and shut off the music. You have to go to FM then back to CD to reset the unit. Obviously its not a big deal because you really aren’t supposed to use the buttons anyway.

GROM
It works through the external CD changer port. Notes: On the later radio software if you press track up or track down on the radio or steering wheel controls the radio will lock up and shut off the music. You have to go to FM then back to CD to reset the unit. Obviously its not a big deal because you really aren’t supposed to use the buttons anyway.

Device Mounting
Now that we have the auxiliary aux adapters out of the way. Some of you may want to keep your device mounted inside of the cabin instead of inside the glove box. There are several ways to do this.
ProClip makes custom Dash Mounts that clip onto 3 different locations on your dash to give you a universal mounting surface for any purpose. When you use these dash mounts along with an iPod holder it places the iPod at a location that is convenient to you. ProClip makes 3 different ones for your car.
