If you would rather purchase the parts separately they are listed below.


1. Radio wiring harness

This is our famous HILO radio installation harness.  It fixes most audio issues when installing a new radio

  • If your car DID NOT come with RNS-E Navigation  need the SRWH-AUD2-HILO
  • If your car came with RNS-E Navigation you need the SRWH-AUD3-HILO

2. Steering Wheel Controls (optional)

This wire translates your factory steering wheel controls for use with your new radio *when used with the harness above

3. Plug and Play Converter (optional but strongly recommended)

Converts the connector on harness 1 into a connection specific to your radio

4. Radio Mounting Kit

This part holds a standard radio in place and fills the gaps around the radio for a factory finish.  It is painted to match the factory dashboard

5. AM/FM Antenna adapter

This adapter converts the connector and powers you Audi antenna booster.

  • If your car DID NOT come with RNS-E Navigation you need the AAA-VWAUD2
  • If your car came with RNS-E Navigation you need the AAA-VWAUD5

6. Aftermarket Microphone for factory location (optional)

Our microphone is made for aftermarket radios and designed to perfectly fit in the hidden factory location inside the overhead panel of cars that were equipped with Onstar.

7. SiriusXM Antenna Adapter (optional)

Most 2002-2005 US Audi A6’s have a Sirius XM antenna on the roof.  This wire is connected to the tuner in the trunk.  The SAA-SIR600 is made to connect to the factory Sirius XM antenna cable in the trunk on the left side.

All SiriusXM ready radios require this external tuner in order to listen to SirusXM.

8. GPS Antenna Adapter (optional)

All aftermarket radios with GPS or Wireless CarPlay/Android Auto come with an external GPS antenna.
All 2002-2005 Audi A6’s with a factory GPS radio  have a factory GPS antenna that you can use with your aftermarket radio using this adapter.

If your 2002-2005 US A6 did not have factory navigation the antenna on the roof still may have a GPS antenna cable.  The cable is on the drivers side behind the Sirius tuner.

You will need this extension cable  to connect to this cable.  And also the cable above to connect to the radio.

9. Radio Removal Keys

The Concert II radio needs 2 keys the rest of the radios need 4 keys to be removed. 

10. Panel Pry Tools (optional)

These tools come in handy when removing the cars interior trim.


These are the radios we recommend for your car.

If you have the RNS-E radio this video is for you.  The video above covers the full installation on cars without RNS-E but this video covers the wiring.
