How to Install Audi MMI Updates – Complete Installation Guide

Installing an Audi MMI update is not difficult once you know which infotainment system is installed in the car and which procedure belongs to it.

The biggest mistake is assuming that every Audi MMI update works in the same way.

It does not.

Audi has used several generations of infotainment systems, including MMI 2G, MMI 3G, RMC, MIB1, MIB2, MH2p and MIB3. Depending on the platform, an update may use:

• CD or DVD media,
• an SD card,
• a USB drive,
• a system update menu,
• a service or engineering menu,
• or a platform-specific update process.

The first step is therefore not copying files to an SD card.

The first step is identifying the system.

If you do not know which MMI is installed in your Audi, use our complete Audi MMI identification guide.

Quick Answer: How Do You Install an Audi MMI Update?

The general process is:

Identify your Audi MMI system
↓
Check the full current software version
↓
Confirm the correct firmware or map package
↓
Download and unpack the files
↓
Prepare the correct SD card / USB / CD media
↓
Follow the installation manual for your MMI generation
↓
Allow the update to finish completely
↓
Restart and verify the new software or map version

The important part is that the actual installation procedure changes between MMI generations.

Do not use an MMI 3G tutorial for MIB2, and do not use a MIB2 procedure for MH2p.

Step 1: Identify Your Audi MMI System

Before installing anything, check the full software or media version displayed by the infotainment system.

Common Audi software prefixes include:

Software prefix	Audi infotainment system
BNav_	MMI 3G Basic
HNav_	MMI 3G High
HN+_ / HN+R_	MMI 3G Plus
RMC_	Audi RMC
MHIG_	MIB1 High
MSTD_	MIB1 Standard
MHI2_	MIB2 High
MHI2Q_	MIB2 High
MHS2_	MIB2
MH2p_	newer MIB2 / MIB2+ platform
MHI3_	MIB3

For example:

HN+_EU_AU3G_P0814

indicates a completely different infotainment platform from:

MHI2_ER_AU57x_P3634

Even though both may be installed in Audi vehicles.

Knowing that the car is an:

Do Not Identify MMI Only by Car Model

Audi A6 2016

is not enough.

The same Audi model can have different infotainment systems depending on:

• production year,
• market,
• equipment,
• navigation option,
• hardware revision,
• and factory configuration.

Always check the software version first.

Step 2: Check the Complete Current Software Version

Do not record only the last few digits.

For example, this:

MHI2_ER_AU57x_P3634

is useful.

This:

3634

is not enough.

The complete train tells you which firmware family, region and update path you are dealing with.

If you already know your software version, you can use our Audi MMI update compatibility checker to see which firmware, navigation maps or upgrade packages are available.

Step 3: Confirm That You Have the Correct Update

Before preparing any media, make sure the update actually matches your system.

Check:

• MMI generation,
• full current firmware version,
• region,
• vehicle model where relevant,
• target firmware,
• navigation region,
• and any required intermediate update.

A newer version number does not automatically mean it is compatible.

For example:

MHI2_
MHI2Q_
MHS2_
MH2p_

are all associated with later Audi infotainment systems, but they do not use the same firmware.

If you still need the correct update package, see our guide:

Where to Download Audi MMI Firmware & Software Updates

Step 4: Download and Unpack the Update Files Correctly

One of the most common causes of Audi MMI update problems is incorrect file extraction.

Do not normally copy the downloaded ZIP, RAR or 7z archive directly to the SD card or USB drive.

The files need to be extracted first.

A common mistake looks like this:

SD CARD
└── firmware-package.zip

or:

SD CARD
└── firmware-folder
    └── firmware-folder
        └── update files

The MMI may then report that no update media is available.

The exact expected folder structure depends on the update package and infotainment system.

We have a separate guide explaining this process:

How to unpack Audi MMI update files

Step 5: Use the Correct SD Card, USB Drive or Disc

Different Audi infotainment systems use different update media.

A simplified overview:

MMI system	Typical update media
MMI 2G	CD/DVD depending on update
MMI 3G Basic	SD card
MMI 3G High	SD card
MMI 3G Plus	SD card
RMC	SD card depending on update
MIB1	SD card / platform-specific media
MIB2	SD card or USB depending on unit/update
MH2p	platform-specific USB/update media
MIB3	system-specific update method

Always follow the procedure provided for the exact platform.

Do not assume that because one Audi accepts an update from SD card, every Audi does.

For SD card preparation questions, also see:

What SD card size should I use for Audi MMI updates?

Step 6: Make Sure the Car Has Stable Power

Firmware updates can take time.

The infotainment unit may reboot several times during the process and individual components can be updated separately.

The update should not be interrupted because the battery voltage becomes too low.

For longer firmware procedures, particularly on older MMI systems, using suitable battery support is a sensible precaution.

Do not deliberately switch the MMI off while firmware is being installed.

Step 7: Use the Correct Installation Guide for Your MMI

This is the most important part of this article.

There is no single universal Audi MMI installation sequence.

Choose the procedure below that matches your infotainment system.

How to Install MMI 2G Updates

MMI 2G is one of the older Audi infotainment generations.

Firmware installation normally uses optical media rather than the SD-card procedures used by newer MMI generations.

A firmware package may require several discs and a specific installation sequence.

If you have MMI 2G High, use our dedicated tutorial:

Audi MMI 2G High – How to Update Firmware

We also have a separate guide covering preparation of update media:

MMI 2G High – How to Prepare a CD with Firmware / Maps Update

Do not follow MMI 3G SD-card instructions on MMI 2G.

How to Install MMI 3G Firmware

MMI 3G includes several different systems:

• MMI 3G Basic — BNav_
• MMI 3G High — HNav_
• MMI 3G Plus — HN+_ / HN+R_

Firmware installation normally uses an SD card and the MMI software update interface.

However, the exact firmware package and update path depend on the current software version.

For the complete step-by-step procedure, use:

Audi MMI 3G Firmware Update – Complete Guide

That tutorial covers the detailed installation process for MMI 3G systems.

Important: MMI 3G Is Not MIB2

Do not follow an MIB2 tutorial just because both systems can use SD cards.

MMI 3G and MIB2 are completely different infotainment generations.

How to Install MMI 3G Navigation Maps

Firmware and navigation maps are separate updates.

A map package changes the navigation database, while firmware updates the software running the MMI.

Depending on the system, you may need to:

1. check the current firmware,
2. update firmware if required,
3. install the navigation database,
4. activate the maps where required.

For general map installation information, use:

How to Update Maps in Audi MMI

For MMI 3G Basic specifically:

How to Update Maps in MMI 3G Basic

How to Install Audi RMC Updates

RMC is its own infotainment platform.

It should not be treated as MMI 3G even if some menus or controls appear similar.

RMC firmware versions normally begin with:

RMC_

Before updating an RMC unit:

• verify the full firmware version,
• confirm the region,
• check that the package is specifically intended for RMC,
• and use the instructions supplied for that update.

Do not install BNav, HNav or HN+ firmware on an RMC system.

How to Install Audi MIB1 Updates

MIB1 systems can include software prefixes such as:

MHIG_

and:

MSTD_

MIB1 is a newer architecture than MMI 3G.

Its update structure, menus and firmware files are therefore different.

Before installing firmware or maps:

• verify the exact MIB1 platform,
• check the software train,
• confirm the update package,
• and use the system-specific installation procedure.

Do not assume MIB2 instructions also apply to MIB1.

How to Install Audi MIB2 Firmware

Audi MIB2 includes several firmware families.

Common examples include:

MHI2_
MHI2Q_
MHS2_

This is one of the most important areas where users make compatibility mistakes.

For example, an update intended for:

MHI2_ER_AU57x_

should not automatically be treated as compatible with:

MHI2Q_ER_AUG22_

even though both are commonly referred to as MIB2 High.

For MIB2 firmware installation, use:

Audi MIB2 Firmware Update – Complete Installation Guide

That page should be your main technical reference for the actual MIB2 update procedure.

How to Install Audi MIB2 Navigation Maps

MIB2 map updates have their own installation procedure.

Do not confuse the navigation database with firmware.

For the dedicated map procedure, use:

Audi MIB2 Map Update Manual

Depending on the system and package, navigation activation or licensing may also be required.

How to Install MH2p Firmware

MH2p is found in newer Audi infotainment systems and normally uses a software prefix beginning with:

MH2p_

For example:

MH2p_ER_AUG35_P2711

or another train from the same platform.

MH2p should not be updated using MHI2 or MHI2Q instructions.

For the system-specific procedure, use:

MH2p – How to Update Firmware

What About Audi MIB3?

MIB3 uses a newer software architecture.

Versions may include:

MHI3_

MIB3 should not be treated as an extension of MIB2.

The exact update method can depend on:

• vehicle model,
• firmware family,
• region,
• installed hardware,
• and the type of update being performed.

Always verify the exact MIB3 package and installation procedure before starting.

If you are unsure whether your Audi has MIB2 or MIB3, see:

Audi MIB2 vs MIB3 – How to Identify Your MMI System

Firmware Update vs Map Update

This causes a lot of confusion.

Firmware Update

Firmware changes the software running the infotainment unit.

Examples of firmware trains include:

HN+_EU_AU3G_K0942_6
MHI2_ER_AU57x_K3663_1
MHI2Q_ER_AUG22_P5092

Navigation Map Update

Maps update the navigation database.

They contain newer:

• roads,
• addresses,
• intersections,
• motorway changes,
• points of interest,
• and other navigation data.

Installing firmware does not automatically mean you have installed newer maps.

Installing maps does not automatically update the MMI firmware.

Should You Install Firmware Before Maps?

Sometimes.

It depends on the current MMI version and the navigation database you want to install.

On some older systems, newer map releases may require a minimum firmware version.

A typical process could therefore be:

Check current MMI
↓
Check current firmware
↓
Update firmware if required
↓
Install maps
↓
Activate maps if required

But this should not be treated as a universal rule for every Audi.

Always follow the instructions for your specific platform.

Do You Need the Hidden Green Menu?

Not for every Audi MMI update.

This is another area where older guides can create confusion.

The Hidden Green Menu is particularly relevant to certain MMI 2G/3G procedures and configuration tasks.

It is not a universal requirement for MIB2, MH2p or MIB3 updates.

If your specific MMI 3G procedure requires the Green Menu and it is not enabled, use our dedicated activation guide rather than assuming every system needs it.

Should You Use the “User Defined” Update Mode?

Only when the instructions for your exact system tell you to do so.

Advanced update options can allow individual components to be selected or excluded.

They should not be changed randomly.

For normal updates, follow the procedure supplied with the compatible firmware package.

If a guide specifically instructs you to exclude or select a particular module, follow that system-specific instruction.

What Should You Do If the MMI Does Not Detect the Update?

If the MMI reports that the update medium is unavailable or cannot find update files, first check:

• whether the archive was unpacked,
• whether an additional folder level was created,
• whether files are in the correct location,
• whether the SD/USB filesystem is supported,
• whether the media is compatible,
• whether you downloaded the correct platform,
• and whether the update menu matches your MMI generation.

We have a separate troubleshooting guide:

MMI Can’t Find Update – How to Copy Files onto the SD Card

What If the Update Fails?

Do not immediately try random firmware packages.

Record:

• the exact MMI version,
• firmware you attempted to install,
• percentage where the update stopped,
• error code,
• component name,
• and what the MMI displays after reboot.

Some update failures have dedicated recovery procedures.

For example, MMI 3G and MIB2 have very different recovery methods.

The correct fix depends on the platform and error.

What If the MMI Shows Error 03276 After Updating?

MMI 3G owners may encounter:

03276 - Please Check Software Version Management

after a firmware update.

That does not mean you should reinstall the whole firmware blindly.

Use the dedicated procedure:

03276 – Please Check Software Version Management – How to Remove

What If BOSE Stops Working After an MMI 3G Firmware Update?

BOSE-equipped MMI 3G vehicles require additional care during certain firmware procedures.

If the audio system has already been affected after an update, use:

How to Rescue BOSE Audio System After Firmware Update

This is another reason why a system-specific installation guide is preferable to a universal “click update and wait” procedure.

Can Firmware Activate Apple CarPlay?

Not automatically.

On compatible MIB systems, firmware may be one part of a CarPlay / Android Auto activation process.

Additional activation, licensing, patching or configuration may still be required.

Older MMI 2G and MMI 3G systems do not become native CarPlay systems simply by installing newer firmware.

They normally require additional retrofit hardware.

If your goal is not simply updating firmware but upgrading the functionality of the MMI, see:
