Radio Wiring Harness

Main Radio wiring harness

If your car came with the RNS-E Concert II+ or Symphony II+ radio you need this harness.

If your car came with the Concert II or Symphony II radio you need this harness.

Steering Wheel Control Wire

The harnesses above cannot use your factory steering wheel controls without this wire.  It programs the small box for the radio you are installing.
If you are installing a android radio use the universal one.

Plug and Play Converter

The harnesses below have an ISO connector instead of bare wires on the end of them.  This plug and play converter will go straight into some radios without cutting a single wire.  Check the google sheet on this products page to see if your radio will connect directly of of you will need to buy a converter to do a plug and play easy peasy installation.

Radio Mounting Kit

This part hold the radio in place and fills the gaps around the radio for a factory finish.
We do not have a kit for the 2.5″ tall radios.


AM/FM Antenna adapter

The factory antenna in your car is not the same shape as your aftermarket radio.  These adapters convert the shape and power the factory antenna booster.

If your car came with the RNS-E or Symphony II+ radio you need this antenna adapter

If your car came with the Concert II or Symphony II radio you need this antenna adapter.

Factory Fit Microphone

Custom Factory Fit Microphone

This part is made to fit in your cars factory microphone location.  Not only will you get better sound quality but since it is mounted behind the factory panel you will not have to see an ugly mic hanging off your headliner.

This is the mic used for the B6 convertible.  We also sell this without the microphone if you want to use the guts of the microphone that came with your radio.  When using the guts of the microphone that came with your radio you can pass the mic through the motion sensor hole and use this on all 2002-2008 A4’s.  IT also saves you some money.

SiriusXM Antenna Adapter

All 2006-2013 US Audi A3’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.
No products found

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

GPS Antenna Adapter

All aftermarket radios with GPS or Wireless CarPlay/Android Auto come with an external GPS antenna.
All 2006-2013 Audi A3’s with a factory GPS radio have a factory GPS antenna that you can use with your aftermarket radio using this adapter.


If your US A3 did not have factory navigation the antenna on the roof still has a GPS antenna cable.  The cable is on the Drivers side behind the Sirius tuner.  (See video in videos section)

You will need this extension cable to connect to this cable.


Backup Camera


This camera replaces the handle in your hatch

Radio Removal Keys

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

Panel Pry Tools

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 or Symphony II+ radio this video is for you.  But it covers so much that everyone should watch it.

This videos is in an A6 but it covers the wiring for the Symphony II and Concert II radio the best out of all my videos.
