Audi MMI 3G Apple CarPlay & Android Auto Module Installation Guide

This step-by-step installation guide explains how to install our Apple CarPlay and Android Auto hardware interface in Audi vehicles equipped with MMI 3G Basic, MMI 3G High or MMI 3G Plus.

The installation covers the physical module connection, LVDS wiring, main MMI harness, DIP switch configuration, AUX audio activation, Wi-Fi antenna placement and USB extension routing.

This guide is for a hardware CarPlay / Android Auto retrofit. If your Audi has a compatible MIB2 MHI2 or MHI2Q system, CarPlay may instead be activated through software without installing this external interface.

Not sure which MMI system you have? Check your MMI version before starting:

Step 5 – Configure the DIP Switches

Before you will test module, make sure that dip switch is correctly set.

So if you have AUDI A4 2014 you dip switch should looks like: 

1 – OFF
2 – OFF
3 – OFF
4 – OFF
5 – OFF
6 – OFF
7 – ON (if you have parking enabling button in climate panel)
8 – ON (if you car is equipped with bluetooth system).

BE AWARE!! WE ARE ALWAYS ATTACH CORRECT DIP SWITCH SCHEME WITH YOUR UNIT, PLEASE DO NOT BASED ON DIP SWITCH SCHEME FROM THIS MANUAL HERE, ONLY TO ATTACHED PAPER.

Step 6 – Enable AUX Audio for the CarPlay Module

If you have already tested system, you might noticed that there’s no sound.. If you car is equipped with AMI port in glovebox now we will enable AUX – but no worries do not need connect anything to the AUX It must be enabled for our box – it will be already connected to the AUX by CAN.

You need Hidden Green Menu access – if you don’t have, here we got solution – CLICK.

Audi MMI 3G AUX activation procedure.

1. Turn key into II position and wait for the MMI 3G system to start. You can also use keyless buttons. 

2. Wait around 5 minutes and press and hold buttons MENU(or SETUP) and CAR.

3. After couple of seconds hidden green menu will appear. You can now release the buttons.

4. Navigate to diagnose → settings → AMI/AUX.

5. Change the value of “AUX” “disabled” to “enabled” preserving other options.

6. Press RETURN and CAR buttons at the same time to exit hidden green menu.

7. Restart the MMI

If you are using Apple CarPlay / Android Auto module please remember to set media source as AUX!

Step 7 – Install the Wi-Fi Antenna and USB Extension

Antenna has quite strong signal, it can be hidden with box behind unit, or if you wish you can stick it to under gear selector. 

For USB we recommend use extension lead and drag to the armrest.

Disassembly of the central tunnel

Now you can drag wifi antenna to the main tunnel and stick on to side of the tunnel. 

Similar with USB extension lead but you can drag it near seat straight to the armrest. 

Step 8 – Test Apple CarPlay and Android Auto

Now you can test module if it works. Start MMI, wait few seconds and push and hold NAV button for few seconds (you should hear CLICK sound from the box) on mmi you should see that module has started. 

On the screen you’ll see Wireless its for wireless apple carplay, you can connect there your iPhone (all details to connect should be there).

Wired – it’s for wired connection and should works straight after you connect your android / iPhone via usb cable.
