How to Connect Android Auto Wirelessly in Audi

Wireless Android Auto lets your phone connect to the Audi infotainment system automatically without plugging in a USB cable every time you enter the car.

However, there is one important detail that causes a lot of confusion:

having Wi-Fi and Bluetooth in your Audi does not automatically mean the vehicle supports Wireless Android Auto.

There are several completely different Audi configurations:

• factory Wireless Android Auto
• factory wired Android Auto only
• MIB2 with Android Auto available after software activation
• older MMI without native Android Auto
• wired Android Auto converted to wireless with an adapter
• older MMI upgraded with an external CarPlay / Android Auto interface

Before trying to connect your phone, identify which situation applies to your Audi.

Quick Answer

If your Audi already supports factory Wireless Android Auto, keep Bluetooth, Wi-Fi and Location enabled on the phone, pair the phone with the vehicle through Bluetooth and follow the Android Auto prompts on both screens.

If your Audi has wired Android Auto only, Bluetooth pairing alone will not magically make it wireless. You either continue using USB or add a compatible wired-to-wireless adapter.

If your Audi does not have Android Auto at all, you first need to add or activate Android Auto. The correct method depends on the MMI generation.

Google currently requires a compatible vehicle/head unit and a compatible Android phone with 5 GHz Wi-Fi support for Wireless Android Auto. Android 11 or newer supports wireless projection on compatible phones.

First – Find Out What Your Audi Actually Supports

Do not start by searching the Wi-Fi networks available in the car.

First determine whether your Audi has:

1. Native Wireless Android Auto

2. Wired Android Auto

3. Android Auto-capable MIB2 but feature not activated

4. Older MMI without native Android Auto

These require completely different solutions.

If you do not know which MMI system you have:

Audi MMI Versions – Why They Matter

Typical Audi software prefixes include:

BNav_
HNav_
HN+_
HN+R_

RMC_

MHIG_

MHI2_
MHI2Q_
MHS2_
MH2p_

MHI3_

You should not choose an Android Auto solution from the Audi model year alone.

For example, two Audi A6 vehicles can have completely different infotainment hardware and therefore require completely different Android Auto upgrades.

Scenario 1 – Your Audi Already Supports Wireless Android Auto

This is the easiest situation.

According to Google’s current setup procedure, the first wireless connection begins with Bluetooth pairing. You should leave:

Bluetooth
Wi-Fi
Location Services

enabled on the phone during setup.

Step 1 – Start the Audi

Park the vehicle safely and switch on the infotainment system.

Do the initial pairing while stationary.

Step 2 – Enable Wireless Functions on the Phone

Make sure:

Bluetooth = ON
Wi-Fi = ON
Location = ON
Mobile data = available

You normally do not need to manually connect to the vehicle’s Wi-Fi hotspot first.

Step 3 – Pair the Phone Through Bluetooth

Open Bluetooth settings on your Android phone.

Depending on the Audi system, start adding a new telephone through:

Telephone
Connections
Connected devices
Audi Smartphone Interface

or the relevant menu in your MMI.

Select the Audi from the phone or the phone from the MMI and confirm the matching pairing code.

Google specifically states that the initial Wireless Android Auto setup requires Bluetooth pairing.

Step 4 – Accept Android Auto Permissions

Follow the prompts displayed on:

• the phone
• Audi MMI display

Allow the required Android Auto permissions.

Step 5 – Start Android Auto

After pairing, Wireless Android Auto should normally launch automatically or become available from the Audi Smartphone Interface menu.

After the first successful setup, the phone should reconnect automatically on future journeys.

Do I Need to Download the Android Auto App?

On current Android versions, normally no.

Android Auto is integrated into Android and Google specifically states that you do not need to download a separate Android Auto application.

This is one of the important corrections to the old version of this tutorial.

If Android Auto needs updating, the phone may request an update during setup.

What Phone Do I Need for Wireless Android Auto?

Google’s current requirements for Wireless Android Auto include:

• compatible Android phone
• active mobile-data connection
• 5 GHz Wi-Fi support
• compatible wireless Android Auto vehicle or receiver

Wireless projection is supported by phones running Android 11 or newer, provided the hardware and regional requirements are also satisfied.

So:

Android 11+
+
5 GHz Wi-Fi
+
compatible vehicle/head unit
=
basic Wireless Android Auto requirements

The vehicle side is just as important as the phone.

Scenario 2 – Your Audi Has Wired Android Auto Only

This is extremely important for Audi owners.

If Android Auto works when you connect the phone to the Audi USB port but stops as soon as you unplug the cable, your car may simply support wired Android Auto only.

That is not a fault.

You have:

factory Android Auto
+
compatible USB hardware
+
no native wireless projection

Pairing another Bluetooth profile or manually connecting to the Audi Wi-Fi network will not necessarily convert it to Wireless Android Auto.

How to Convert Wired Android Auto to Wireless

If Android Auto already works through USB, the easiest upgrade can be a wired-to-wireless adapter.

Our current adapter is available here:

Mib2 Wired to Wireless Apple CarPlay / Android Auto extension kit

Important requirement:

the vehicle must already have working wired Apple CarPlay or Android Auto.

The adapter does not create Android Auto capability in an MMI system that never had it.

Its job is:

existing wired Android Auto
↓
wireless adapter
↓
Wireless Android Auto

not:

no Android Auto
↓
adapter
↓
Android Auto magically appears

That distinction should be very clear. The current product itself requires OEM wired CarPlay/Android Auto before installation.

Typical Wireless Adapter Setup

For a compatible Audi with working wired Android Auto:

1. Confirm Android Auto works normally through USB.
2. Disconnect the phone.
3. Connect the wireless adapter to the USB port normally used for Android Auto.
4. Enable Bluetooth and Wi-Fi on the phone.
5. Pair the phone with the adapter.
6. Follow the adapter setup instructions.
7. Wait for Android Auto to launch.
8. Restart the vehicle and confirm automatic reconnection.

Do not troubleshoot the adapter until you have confirmed that wired Android Auto works without it.

That is the baseline test.

Scenario 3 – MIB2 Has No Android Auto Yet

Some compatible Audi MIB2 systems can support factory-style CarPlay and Android Auto but the feature may not currently be activated.

Common compatible families include:

MHI2_
MHI2Q_

On supported hardware, Android Auto and Apple CarPlay can be enabled through software activation.

Our installation guide is here:

Audi MIB2 CarPlay / Android Auto Activation & Lifetime Map License – Installation Guide

Activation solution:

Mib2 CarPlay / Android auto activation script + lifetime map license / EU conversion

But note the important distinction:

the software activation provides the supported factory wired CarPlay / Android Auto functionality.

The MIB2 activation guide itself explicitly notes that this functionality is wired and requires connection through the correct USB port.

If you want wireless operation afterward:

MIB2 activation
↓
wired Android Auto works
↓
add wired-to-wireless adapter
↓
Wireless Android Auto

Adapter:

Mib2 Wired to Wireless Apple CarPlay / Android Auto extension kit

Does MIB2 Firmware Alone Make Android Auto Wireless?

No.

Do not confuse:

Android Auto activation

with:

Wireless Android Auto

or:

firmware update

They are different things.

On compatible MHI2 / MHI2Q systems:

software activation
→ enables supported Android Auto / CarPlay functionality

wireless adapter
→ converts an already working wired connection to wireless

A random firmware update should not be sold as a method for converting wired Android Auto into wireless Android Auto.

Scenario 4 – Your Audi Has MMI 3G

If your software begins with:

BNav_
HNav_
HN+_
HN+R_

you have an older MMI 3G-family system.

These systems were designed before native Android Auto became part of Audi’s infotainment architecture.

You cannot turn an MMI 3G unit into native Android Auto simply by:

• pairing Bluetooth
• joining an Audi hotspot
• installing navigation maps
• enabling the Green Menu
• installing newer MMI 3G firmware

For MMI 3G, the normal solution is an additional hardware interface.

That interface works alongside the original Audi MMI and adds the smartphone-integration layer.

Wireless Android Auto vs Wired Android Auto

We are moving the useful part of the old comparison article here.

Neither connection method is universally better.

Wireless Android Auto

Advantages:

• no need to connect a cable every journey
• automatic reconnection after initial pairing
• cleaner interior
• convenient for short journeys
• phone can remain in a pocket or bag

Disadvantages:

• increased phone battery use
• wireless connection adds another troubleshooting layer
• Wi-Fi/Bluetooth interference can affect connection quality
• the phone is not automatically charging

Wired Android Auto

Advantages:

• simple direct connection
• phone charges while connected
• useful as a diagnostic baseline
• avoids some wireless-interference problems

Disadvantages:

• cable required
• USB connector and cable can wear
• phone must normally be plugged in for every journey

Which One Should You Use?

For everyday short trips:

Wireless Android Auto

is usually more convenient.

For:

• long journeys
• charging
• troubleshooting
• diagnosing random disconnects

a wired connection remains very useful.

I would therefore never eliminate the wired option completely.

Does Wireless Android Auto Use Bluetooth or Wi-Fi?

Both technologies are involved.

The first setup is initiated through Bluetooth pairing, while the higher-bandwidth projection uses Wi-Fi.

This is why Google recommends keeping:

Bluetooth
Wi-Fi
Location

enabled during wireless setup.

Do not interpret the presence of an Audi Wi-Fi hotspot as proof that Wireless Android Auto is supported.

An Audi can have Wi-Fi functionality for other purposes without supporting Android Auto wireless projection.

Do I Connect Manually to the Audi Wi-Fi Network?

Normally not as the basic factory Wireless Android Auto setup.

This is another correction to the original 2021 article.

Google’s current setup procedure tells the user to initiate the first connection through Bluetooth pairing and let the Android Auto process establish the required connection.

A particular retrofit module or adapter may have its own Wi-Fi setup procedure, so follow the instructions supplied with that hardware.

Why Won’t Wireless Android Auto Connect?

Start with the simplest tests.

1. Confirm that wired Android Auto works

If your system is supposed to support Android Auto through USB, connect the phone directly.

If wired Android Auto itself fails, do not blame wireless functionality yet.

2. Check Bluetooth

Remove old Audi/adapter pairings and pair again.

3. Check Wi-Fi

Make sure Wi-Fi is enabled on the phone.

4. Check Location

Keep Location enabled during initial setup.

5. Restart the phone

A simple restart can clear a stuck wireless session.

6. Restart the MMI or adapter

Restart the infotainment system according to the correct procedure for your MMI generation.

7. Forget the connection and pair again

Remove:

• Audi Bluetooth profile
• Android Auto vehicle
• wireless-adapter pairing

where applicable, then start again.

8. Verify compatibility

Do not assume the phone, Audi and adapter support the same connection method.

Wireless Android Auto Connects but Keeps Disconnecting

If the connection starts normally but repeatedly drops, determine whether the fault exists:

only wirelessly

or:

wired and wireless

Wireless drops, wired stable

Investigate:

• phone Wi-Fi/Bluetooth
• adapter
• wireless interference
• pairing
• adapter firmware
• power to the USB port

Wired and wireless both fail

Investigate:

• Android Auto configuration
• Audi Smartphone Interface
• USB hardware
• MMI software
• phone compatibility

This split saves a lot of time.

Android Auto Does Not Start Automatically

Check:

• Bluetooth connection is established
• Wi-Fi is enabled
• Android Auto permissions are granted
• the phone is allowed to connect to the vehicle
• the correct device is selected in Audi Smartphone Interface
• old phones are not taking priority

If you use a wireless adapter, also check that the adapter is receiving power when the MMI starts.

Android Auto Works With Cable but Adapter Does Not

This is useful diagnostic information.

It proves that:

phone
+
Audi Android Auto
+
Audi USB data connection

can work.

Now focus on:

• adapter pairing
• adapter power
• wireless compatibility
• adapter firmware
• Bluetooth/Wi-Fi state

rather than reflashing the Audi MMI.

Wireless Android Auto Works but There Is No Sound

If navigation and Android Auto appear correctly but audio does not play:

• check selected audio source
• increase media volume on the phone
• verify Audi media volume
• check retrofit-module audio routing if using external hardware

On older MMI retrofit interfaces, audio routing can be different from factory MIB2 Android Auto.

Do not use one universal audio fix for every MMI platform.

Can I Add Wireless Android Auto to Any Audi?

Potentially, but not with one universal method.

A useful decision tree is:

Does Audi already have Wireless Android Auto?
YES
→ pair phone normally

NO
↓
Does wired Android Auto work?
YES
→ wired-to-wireless adapter

NO
↓
Is it compatible MIB2 MHI2/MHI2Q?
YES
→ activate Android Auto
→ verify wired operation
→ optionally add wireless adapter

NO
↓
Is it older MMI 3G?
YES
→ external CarPlay / Android Auto interface

Unsure?
→ identify MMI first

How Do I Check Whether My Audi Has MIB2?

Look at the complete software version.

Examples:

MHI2_ER_AU57x_...
MHI2_ER_AUG11_...
MHI2_US_AU57x_...
MHI2Q_ER_AUG22_...
MHI2Q_US_AUG22_...

Do not identify MIB2 simply from the model year.

Common Mistakes

Assuming Bluetooth means Wireless Android Auto

Bluetooth audio and phone calls are not the same as Android Auto projection.

Assuming Audi Wi-Fi means Wireless Android Auto

A Wi-Fi hotspot can exist for unrelated online/connectivity functions.

Buying a wireless adapter when Android Auto is not activated

The adapter requires working wired Android Auto first.

Updating firmware randomly

Firmware should be selected for the exact MMI system and should not be used as a generic wireless-connectivity fix.

Treating MMI 3G like MIB2

MMI 3G requires a different retrofit approach.

Connecting to random Wi-Fi networks manually

Use the pairing workflow specified by Android Auto or your particular adapter/interface.
