Keeping an Audi MMI system up to date starts with one thing: identifying the exact firmware branch installed in the car.
Two Audi vehicles from the same year can use completely different infotainment systems, so choosing firmware only by model, production year or screen appearance is not reliable.
For European Audi vehicles, you may encounter software families including:
BNav_
HNav_
HN+_
HN+R_
RMC_
MENT_
MSTD_
MHIG_
MHI2_
MHI2Q_
MHS2_
MH2p_
MHI3_
Each family belongs to a different generation or hardware platform.
Firmware designed for one branch must not be installed on another simply because the vehicle model or model year looks compatible.

Newer MIB2 / MIB2+ systems:
MH2p_
MIB3:
MHI3_
The complete software train is more important than the Audi model name.
Audi MMI 3G Basic – BNav Firmware
MMI 3G Basic can normally be identified by a firmware version beginning with:
BNav_
For European systems, a common software branch is:
BNav_EU_
One of the main firmware releases currently available for this platform is:
BNav_EU_K0260_1_D1
Audi product number:
8R0 906 961 DP
Firmware:
This firmware is intended for compatible MMI 3G Basic systems.
Do not install it on:
HNav_
HN+_
HN+R_
RMC_
MHI2_
MHI2Q_
MHS2_
If your main software version starts with BNav_EU_, verify the complete current version before updating.
MMI 3G Basic also uses its own navigation map family. Firmware and navigation maps are separate packages.
Current European map information:
Detailed map installation guide:
Audi MMI 3G High – HNav Firmware
MMI 3G High normally uses a software train beginning with:
HNav_
European units commonly use:
HNav_EU_
One of the main European firmware releases available for this platform is:
HNav_EU_K0257_6_D1
Firmware:
HNav firmware must not be confused with BNav or HN+ software.
For example:
BNav_EU_K0260_1_D1 = MMI 3G Basic
HNav_EU_K0257_6_D1 = MMI 3G High
HN+_EU_AU3G_K0942 = MMI 3G Plus
They are different systems even though all three belong to the wider MMI 3G generation.
European MMI 3G High navigation maps are also separate from firmware.
Information about the 6.36.0 European navigation database:
Audi MMI 3G Plus – HN+ Firmware
MMI 3G Plus uses several software branches.
On vehicles such as selected Audi A4, A5, Q5 and Q7 models you may see:
HN+EU_AU3G
A well-known European firmware version for this branch is:
HN+_EU_AU3G_K0942
Product number:
8R0 906 961 FC
Firmware:
Do not treat every version beginning with HN+ as interchangeable.
The complete train matters.
Audi A1 MMI 3G Plus – AU210 Branch
Audi A1 uses its own MMI 3G Plus software branch.
You may encounter versions beginning with:
HN+EU_AU210
One firmware offered for this branch is:
HN+_EU_AU210_K0900
Product number:
8R0 906 961 EC
Firmware:
The AU210 identifier is important.
Do not install an AU3G firmware package simply because both systems are described as MMI 3G Plus.
Audi MMI 3G Plus – HN+R Firmware
Selected Audi A6, A7, A8 and Q3 vehicles use another MMI 3G Plus family:
HN+R_EU_AU_
Examples you may encounter include:
HN+R_EU_AU_K0942_4
and
HN+R_EU_AU_P1001
These are part of the HN+R platform, but the correct target firmware still depends on the exact existing software and hardware configuration.
Current firmware pages include:
HN+R_EU_AU_K0942_4:
https://mmiupdates.com/product/hnr-eu-au-k0942_4-8r0906961fb-latest-firmware-for-3gp-3g/
HN+R_EU_AU_P1001:
https://mmiupdates.com/product/hnr_eu_au_p1001-latest-firmware-for-3gp-3g/
Do not assume that every HN+R unit can use any HN+R package without checking its update path.
If your MMI displays something such as:
HN+R_EU_AU_P0770
HN+R_EU_AU_K0942_4
HN+R_EU_AU_P1001
enter the complete version into:
What About HN+_EU_AU3G_K0942 and HN+R_EU_AU_P1001?
These two names look similar but describe different MMI 3G Plus branches.
HN+_EU_AU3G_K0942 is commonly associated with the HN+ platform.
HN+R_EU_AU_P1001 belongs to the HN+R platform.
You cannot determine compatibility by comparing only the final number such as K0942 or P1001.
The part before the firmware number is critical.
Audi RMC Firmware
RMC is another Audi infotainment family and should not be confused with MMI 3G.
Its software normally begins with:
RMC_
For European units you may encounter:
RMC_EU_
One important current firmware product is:
RMC_EU_K16158
Firmware:
RMC requires additional care because firmware compatibility can depend on the exact RMC hardware revision.
For RMC_EU_K16158 in particular, check the product requirements and hardware version before installation.
Do not choose RMC firmware using only the vehicle model.
Audi MIB1 Firmware – MENT, MSTD and MHIG
Audi later moved from MMI 3G and RMC to the MIB family.
Early MIB systems may use prefixes including:
MENT_
MSTD_
MHIG_
Legacy European examples you may encounter in Audi software databases include:
MENT_EU_AU_P3120
MSTD_EU_AU_K3151
MHIG_EU_AU_P1531
These are not three versions of the same firmware.
They represent different MIB hardware families.
For example, an Audi A3 equipped with MSTD cannot simply be updated using MHIG firmware.
Always match the complete software train.
Audi MIB2 Firmware – MHI2 and MHI2Q
MIB2 introduced a much larger number of hardware-specific firmware branches.
Common prefixes include:
MHI2_
MHI2Q_
But even those prefixes are not specific enough by themselves.
Examples include:
MHI2_ER_AU57x_
MHI2_ER_AUG11_
MHI2_ER_AUG22_
MHI2Q_ER_AUG22_
The complete branch should remain consistent unless a specific conversion or migration procedure has been verified for the exact hardware.
Examples of firmware currently available in the MMIUpdates catalog include:
MHI2_ER_AU57x_K3663
MHI2_ER_AUG22_K3346
MHI2Q_ER_AUG22_P5092
Different Audi models can use different MIB2 hardware despite having almost identical screens and controls.
For detailed MHI2 and MHI2Q firmware installation information:
Can MHI2 Be Updated to MHI2Q?
No standard firmware update should be treated as a way of turning one hardware family into another.
MHI2 and MHI2Q identify different MIB2 platforms.
Likewise:
MHS2 is not MHI2.
MH2p is not MHI2Q.
MIB3 is not a firmware upgrade for MIB2.
Changing infotainment generation generally requires different hardware rather than simply installing a higher-numbered software package.
Audi MHS2 Firmware
MHS2 is another MIB-based platform found in selected Audi vehicles.
Software versions normally begin with:
MHS2_
Examples include:
MHS2_ER_AU_P0120
MHS2_EU_AU_K0129
MHS2_ER_AU_P0433
MHS2_ER_AU_K0461
MHS2_ER_AU_K0465
MHS2_ER_AU_K0471
MHS2_ER_AU_P1232
MHS2_ER_AU_K1240
MHS2_ER_AU_P1242
MHS2_ER_AU_P2035
A current firmware option is:
MHS2_ER_AU_P2035
MU0235
Firmware:
We also maintain a dedicated MHS2 firmware and navigation guide:
MHS2 should never be treated as MHI2 simply because both systems belong to the MIB2 generation.
Audi MH2p / MIB2+ Firmware
Later Audi models can use MH2p software.
Examples of branches you may encounter include:
MH2p_ER_AUG33_
MH2p_ER_AUG35_
MH2p_ER_AU_
A current example is:
MH2p_ER_AUG35_P2873
Firmware:
There are several MH2p hardware and software branches, so do not select P2873 only because another Audi model uses the same final version number.
Always compare the complete train.
Installation guide:
Audi MIB3 Firmware
Newer Audi vehicles can use MIB3, commonly identified by software beginning with:
MHI3_
MIB3 belongs to a newer hardware generation and must be treated separately from:
MHI2
MHI2Q
MHS2
MH2p
A firmware file designed for MHI3 cannot be used to convert an older MIB2 unit into MIB3.
If your software begins with MHI3_, search specifically for the exact MHI3 software branch installed in the vehicle.
Why the Full Firmware Version Is So Important
A common mistake is sending us only:
Audi A6 2015
or:
Audi Q5 2017
That is not enough to identify the firmware.
Depending on equipment, production date and market, similar vehicles can have different MMI systems.
A useful firmware version looks like:
BNav_EU_P0029_D1
HNav_EU_P0022_D1
HN+_EU_AU3G_P0814
HN+R_EU_AU_P0770
RMC_EU_P12321
MHI2_ER_AUG22_P1234
MHI2Q_ER_AUG22_P4171
MHS2_ER_AU_P1242
MH2p_ER_AUG35_P2711
The beginning of the train identifies the software family.
The final part identifies the particular software release.
Firmware and Navigation Maps Are Different Updates
Firmware is the software that operates the MMI system itself.
Navigation maps are the geographical database used by the navigation system.
They should not be confused.
For example:
BNav_EU_K0260_1_D1 = MMI 3G Basic firmware
5.36.1 / 4G0060884AN = MMI 3G Basic European navigation maps
HNav_EU_K0257_6_D1 = MMI 3G High firmware
6.36.0 / 8R0051884KL = MMI 3G High / Plus European navigation maps
MHS2_ER_AU_P2035 = MHS2 firmware
P350_N60MIBSCALE1 = MHS2 European navigation map package
The fact that a newer map exists does not automatically mean you need to install a different firmware package.
Compatibility must be checked first.
Current European Navigation Guides
If you are looking for maps rather than firmware, use the appropriate map guide.

Does a Firmware Update Add Apple CarPlay or Android Auto?
Usually, firmware and feature activation should be treated as separate operations.
Installing newer firmware does not automatically mean Apple CarPlay or Android Auto will become available.
On some compatible MIB2 systems, the correct firmware is part of the preparation for Audi Smartphone Interface activation, but the exact activation method depends on the hardware and software branch.
Older MMI 3G systems do not gain native MIB2 functionality simply by installing newer firmware.
For compatible older MMI systems, an aftermarket CarPlay / Android Auto interface is another option.
Can I Install Firmware From Another Region?
Do not change firmware region unless you are intentionally performing a supported region conversion.
European, North American and Rest of World configurations can differ in:
navigation data
radio settings
online services
languages
licensing
hardware configuration
software branch
A US-to-Europe conversion is not the same procedure as a normal firmware update.
If your current software starts with a US or NAR branch, do not simply install an EU package because the car is now physically located in Europe.
Should I Always Install the Highest Firmware Number?
No.
A larger number does not automatically mean that the package is correct for your MMI.
For example, comparing:
K0260
K0942
P1001
P2035
P2873
P5092
is meaningless when they belong to different hardware families.
The correct order is:
- Identify the complete current software train.
- Determine the exact MMI family.
- Verify the region.
- Verify the hardware branch.
- Check the supported update path.
- Only then select the target firmware.
Safe Firmware Update Preparation
Before starting any firmware update:
- verify the complete current software version,
- make sure the update package matches the system,
- read the instructions supplied for that exact platform,
- use reliable update media,
- fully extract multipart archives before copying files,
- keep the vehicle electrical system stable,
- and never interrupt the system while firmware is being written.
Do not blindly enable every item in User Defined mode.
Do not copy instructions from a different MMI generation.
Procedures that are correct for MMI 3G may be completely wrong for MIB2 or MH2p.
BOSE and Bang & Olufsen Systems
Audio equipment deserves additional attention during some firmware updates.
Depending on the Audi model, MMI generation, amplifier and update package, BOSE or Bang & Olufsen components may require special handling.
There is no single rule that applies to every Audi.
Do not automatically select or deselect amplifier-related components because a generic online guide tells you to.
Follow the procedure for the exact package and vehicle configuration.
MMI Cannot Find the Firmware Update
If the MMI displays:
No update device found
or does not show the update at all, first check the basics.
A common problem is incorrect archive extraction or an additional parent folder on the SD card.
For example:
SD CARD
└── HN+R_EU_AU_P1001
└── update files
may be wrong if the actual update files are supposed to be located directly at the root of the card.
We have a separate troubleshooting guide here:

Find the Correct Firmware for Your Audi
If you already know the complete software train, the fastest option is our update checker:
Enter the complete version exactly as displayed by the MMI.
For example:
HN+R_EU_AU_P0770
not simply:
P0770
The complete version gives us the information needed to distinguish the platform, hardware family and region.
Browse Audi MMI Firmware Updates
You can also browse the complete Audi firmware catalog:
