Audi MHS2 is a separate MIB2 infotainment platform used in selected Audi A3, A4, A5, Q2, Q5 and related models. If your software version begins with MHS2_, you must use firmware and navigation packages designed specifically for MHS2.
Do not select an update only by Audi model or production year.
The complete software train displayed by the MMI is the most important compatibility information.
Typical European MHS2 versions look like:
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
If your software starts with MHI2_, MHI2Q_, MHIG_, MH2p_, MHI3_, HNav_, HN+_ or BNav_, this is not the correct update family for your system.

What Is Audi MHS2?
MHS2 is commonly referred to as MIB High Scale 2.
Although it belongs to the wider MIB2 generation, it should not be confused with MHI2 or MHI2Q.
These platforms use different:
- firmware packages,
- software trains,
- navigation databases,
- update procedures,
- and activation methods.
This distinction is important.
A file described simply as an “Audi MIB2 update” is not automatically compatible with MHS2.
Always check the complete software version before downloading or installing anything.
How to Check If You Have MHS2
Open the version information screen in your Audi MMI and look for the software version.
If the version begins with:
MHS2_
you have an MHS2-family unit.
European units commonly use software trains such as:
MHS2_ER_AU_
or
MHS2_EU_AU_
For example:
MHS2_ER_AU_P1242
The important part is the complete train, not just the final number.
Do not choose firmware only because another vehicle uses a higher version number.
Supported European MHS2 Firmware Families
Examples of European MHS2 software versions 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
This list should be used to help identify the MHS2 family.
It does not mean that every possible firmware can be installed directly over every older version without checking the required update path.
Before updating, verify:
- your complete current firmware version,
- vehicle region,
- hardware compatibility,
- target firmware,
- and any prerequisites specified for the package.
Audi MHS2 P2035 Firmware Update
One of the main European MHS2 firmware packages currently available on MMIUpdates.com is:
MHS2_ER_AU_P2035
MU 0235
Firmware updates change the software running the infotainment unit.
They are different from navigation map updates.
Depending on the starting firmware and vehicle configuration, a firmware update can provide bug fixes, stability improvements or compatibility improvements.
Firmware package:
Before installing P2035, verify the complete current train.
Do not install P2035 simply because the number is higher than your existing firmware version.
Do I Need P2035 Before Updating the Maps?
Not in every case.
Firmware and maps are separate updates.
If your current MHS2 firmware is already compatible with the target navigation database and activation method, updating firmware only because a newer version exists may not be necessary.
However, some configurations or bundled update procedures may use P2035 as part of the complete upgrade.
If you are unsure, provide the complete software version before ordering.
Audi MHS2 Europe Navigation Maps
For compatible European MHS2 navigation systems, the map package currently available on MMIUpdates.com is:
P350_N60MIBSCALE1 ECE 2024
Map product number:
V03959803PS
Region:
Europe / ECE
System:
MHS2 / MIB High Scale 2
The package is specifically intended for MHS2.
It must not be confused with P470 maps used by compatible MHI2/MHI2Q systems.
Map package:
P350 Europe Map Coverage
The P350 European database includes navigation coverage across a wide range of European countries.
Coverage includes countries such as:
Austria
Belgium
Croatia
Czech Republic
Denmark
Finland
France
Germany
Greece
Hungary
Ireland
Italy
Netherlands
Norway
Poland
Portugal
Romania
Slovakia
Slovenia
Spain
Sweden
Switzerland
Turkey
United Kingdom
and additional supported European territories.
Always check the current product description if coverage of one specific country is essential to you.
MHS2 Map Installation and Activation Are Separate Steps
Copying a newer navigation database to the MMI does not automatically mean that the maps will be licensed correctly.
The map database and map activation should be treated as separate parts of the procedure.
The MHS2 P350 package available on MMIUpdates.com includes a dedicated map activation solution.
Do not use activation scripts designed for MHI2 or MHI2Q simply because all of these systems are commonly described as MIB2.
MHS2 requires an MHS2-compatible procedure.
How the MHS2 Map Activation Works
The P350 package includes dedicated activation files.
The general activation process uses a separate SD card containing the activation files.
The MMI is allowed to boot fully before the activation media is inserted.
During the activation procedure the MMI can restart automatically.
Follow the instructions supplied with the exact package rather than using instructions copied from another MIB platform.
Do not interrupt power while the system is writing configuration or licence information.
How to Install MHS2 Navigation Maps
The general process is:
- Check the complete MHS2 firmware version.
- Confirm that the navigation package matches the system and region.
- Download all archive parts.
- Place all downloaded parts in the same folder.
- Extract the archive using 7-Zip.
- Prepare the required SD card.
- Copy the extracted update contents to the correct level of the SD card.
- Allow the MMI to boot completely.
- Insert the update media.
- Start the update using the MMI software update function.
- Allow the installation to finish without interrupting power.
- Complete map activation using the instructions supplied with the package.
- Verify the new map database after the system restarts.
For multi-part archives, extract from the first archive part only.
Do not extract every .001, .002, .003 file separately.
SD Card Preparation
Use a reliable SD card with enough capacity for the complete package.
After extraction, make sure that the actual update files are placed at the required level of the SD card.
One of the most common reasons an Audi MMI does not detect an update is an incorrect directory structure caused by copying the parent extraction folder instead of its contents.
Also check that:
- the archive extracted without errors,
- all download parts were present,
- the media is readable by the MMI,
- the package is for MHS2,
- and the region matches the unit.
Keep the Vehicle Power Supply Stable
Firmware and navigation updates can take time.
The vehicle should have a stable electrical supply throughout the procedure.
Do not interrupt an update by:
- removing the SD card,
- switching off power unexpectedly,
- disconnecting the battery,
- or restarting the infotainment unit manually.
For longer procedures, suitable battery support is preferable.
Complete MHS2 Firmware + Map Bundle
If your vehicle needs both firmware and navigation updates, a combined MHS2 package is available.
The current European bundle includes:
- MHS2_ER_AU_P2035 firmware,
- P350_N60MIBSCALE1 ECE 2024 navigation maps,
- and the required map activation solution.
Bundle:
A bundle can simplify the process, but compatibility should still be verified against the current software train before installation.
MHS2 vs MHI2 and MHI2Q
This distinction causes a lot of incorrect update attempts.
MHS2:
MHS2_ER_AU_…
MHI2:
MHI2_ER_…
MHI2_US_…
MHI2Q:
MHI2Q_ER_…
MHI2Q_US_…
They are not interchangeable firmware families.
For example, the P470 Europe 2027 navigation package used by compatible MHI2 and MHI2Q systems is not an MHS2 map package.
Likewise, MHI2/MHI2Q lifetime map licence or CarPlay activation scripts should not automatically be used on MHS2.
MHS2 vs MH2p
MH2p is also a separate infotainment platform.
A version such as:
MH2p_ER_AUG35_…
does not use MHS2 firmware or MHS2 P350 maps.
If your firmware starts with MH2p_, use the dedicated MH2p update information instead.
Which Audi Models Can Have MHS2?
MHS2 can be found in selected vehicles including:
Audi A3 / S3 / RS3
Audi A4 / S4 / RS4
Audi A5 / S5 / RS5
Audi Q2 / SQ2
Audi Q5 / SQ5
depending on model year, market and factory equipment.
Do not use this vehicle list as the final compatibility test.
For example, an Audi A4 can use different MMI generations depending on its specification.
Always check the software train.
Can I Select an MHS2 Update by Model Year?
No.
Model and production year can help narrow down the possibilities, but they are not sufficient to select firmware or navigation maps safely.
The software version is much more reliable.
For example:
Audi A4 2018
does not provide enough information.
A version such as:
MHS2_ER_AU_P1242
identifies the infotainment platform much more precisely.
European and North American MHS2 Are Different
Do not install European MHS2 firmware on a North American MHS2 unit simply because both begin with MHS2.
For example:
MHS2_ER_…
and
MHS2_US_…
represent different regional software configurations.
Region changes are not normal firmware updates.
A conversion can involve firmware, navigation databases, licensing, radio configuration and other settings.
Firmware Update vs Map Update
These terms are often confused.
Firmware update:
Changes the operating software of the MHS2 infotainment unit.
Map update:
Changes the navigation database containing roads, addresses and points of interest.
Map activation:
Authorizes the installed navigation database where required.
They are separate operations even when all of them are sold together as one bundle.
Does Updating MHS2 Activate Apple CarPlay?
A navigation map update does not automatically activate Apple CarPlay or Android Auto.
Firmware, navigation maps and smartphone interface activation are separate functions.
Do not assume that installing P2035 or P350 alone enables a feature that was previously inactive.
Compatibility and available activation methods depend on the specific MHS2 configuration.
What to Check After an MHS2 Update
After the update is complete, allow the infotainment system to restart fully.
Check:
- software version,
- navigation database version,
- GPS position,
- map display,
- route calculation,
- voice guidance,
- map activation status,
- Bluetooth operation,
- smartphone connectivity,
- and whether any error message remains.
If firmware was updated, it is also useful to perform a diagnostic scan and check whether any update-related faults were stored.
MHS2 Maps Installed but Navigation Does Not Work
If the new database appears in Version Information but navigation remains unavailable, do not immediately reinstall the entire map package.
Check:
- that the package is for MHS2,
- that the correct European region was installed,
- that the map activation procedure completed,
- that the activation files match the package,
- that the MMI restarted correctly,
- and that the unit has not previously been converted or modified.
A successfully copied database and a valid navigation licence are not the same thing.
MHS2 Update Not Detected
If the MMI does not detect the SD card or update package, check the basics first.
Verify:
- SD card structure,
- archive extraction,
- missing download parts,
- SD card compatibility,
- filesystem used according to package instructions,
- software train compatibility,
- and package region.
Do not start changing engineering menu settings randomly to make an incompatible package visible.
