Audi MMI Firmware Update Guide: Choose the Right Version

Navigating Audi MMI Updates: Find the Right Firmware for Your Vehicle

Updating your Audi’s MMI (Multi-Media Interface) system can seem daunting, especially with the variety of firmware options available. If you’ve visited our shop and are confused by the range of updates, we’re here to guide you through selecting the correct one. From identifying your current firmware to choosing the right maps, we’ll break down the entire process.

Understanding Your Current Firmware Version

Before deciding on an update, it’s essential to know your current firmware version. We’ve created a detailed guide on how to check your MMI version—refer to it to identify the firmware and map version installed on your system.

How to Identify Your MMI Firmware

Your MMI firmware code consists of a unique string, like “HN+_EU_AU3G_P0029” or “MHI2_ER_AUG11_P1234.” Identifying this code accurately is crucial for finding a compatible update.

Choosing the Correct Update for Your Audi MMI

Once you know your firmware version, choosing the correct update becomes more manageable. Let’s break down the key points to help you match your current firmware to the available updates in our store.

Match the Firmware Code

1. Identify Your System Type: Look at the beginning of your firmware code. If your code starts with “HN+_EU_AU3G,” this refers to the MMI 3G Plus system.
2. Confirm System Compatibility: For example, if you have the firmware “HN+_EU_AU3G_P0029,” you should only select updates starting with “HN+_EU_AU3G.”
3. Avoid Cross-System Installation: Different MMI systems are not interchangeable. For instance, an “MHI2” update cannot be installed on a car with “HN+R” firmware.

Specific Cases for Different Audi Models

Each Audi model may have unique compatibility considerations. Here are some key examples:

Audi A6/A7 Updates

• Firmware codes beginning with “MHI2_ER_AU57x” or “MHI2_ER_AUG11” are suitable for Audi A6 and A7 models.
• However, only updates beginning with “AUG11” can replace “AU57x” and vice versa.
• For an A6 equipped with HN+R firmware, an MHI2 update would not be compatible.

Audi A4 Compatibility

The Audi A4 allows for more flexibility in firmware choices. While the same compatibility rules apply, you’ll have multiple options, each tailored to different MMI versions.

Firmware Types and Compatibility

Let’s outline the main firmware types and their associated MMI systems:

1. HNAV_: Used in MMI 3G High systems.
2. HN+_: Pertains to MMI 3G Plus (Audi A4,A5,Q5,Q7).
3. HN+R_: Designed for MMI 3G Plus (Audi A6,A7,A8,Q3)
4. BNAV_: Designed for MMI 3G Basic systems.
5. MHI2 and MHS2: Part of the newer Mib2 system updates.

Each type has a specific compatibility, so selecting an update that begins with your current firmware string is essential.

Checking Compatibility in the Red Engineering Menu

The Red Engineering Menu in your MMI is a helpful tool to confirm firmware compatibility. This menu doesn’t require any additional tools or scripts, but it can be tricky to access. Persistence is key—keep trying until you successfully open the menu and verify the firmware version.

Using Our Update Compatibility Tool

We have developed a unique compatibility tool that simplifies the update selection process. Here’s how to use it:

1. Enter Your Firmware Version: Input the full firmware code (e.g., “HN+R_EU_AU3G_P1234”).
2. View Compatible Updates: The tool will display all available updates compatible with your specific MMI system.
3. Ensure Correct Region: Check if your firmware is designated as ER or US/NAR, as this affects compatibility.

Understanding Region Codes (ER, US, NAR)

The firmware region is critical for compatibility:

• ER: Covers Europe, Australia, New Zealand, and several other regions.
• US/NAR: Designed for North American vehicles, including those in the USA, Canada, and Mexico.

Choosing the Right Maps for Your MMI System

Firmware updates often include map updates, which should be matched to your specific MMI system.

Map Compatibility Based on MMI System

1. HN+ or HN+R: Look for MMI 3G Plus maps.
2. HNAV_: Find maps for MMI 3G High systems.
3. BNAV: Search for MMI 3G Basic maps.
4. MHI2/MHI2q: Choose maps compatible with the Mib2 system.
5. MHS2: Opt for Mib High Scale 2 maps.

Common Questions on Audi MMI Firmware Updates

Why Can’t I Use a Different MMI System’s Firmware?

Firmware compatibility is based on hardware and software limitations specific to each MMI model. Using incompatible firmware could lead to performance issues or, worse, render the MMI system non-functional.

What Should I Do If I Can’t Access the Red Engineering Menu?

Try different button sequences and consult your manual. Persistence often pays off, and once you’re in, verifying your firmware becomes straightforward.

Do All Audi Models Support Mib2 System Updates?

No, Mib2 systems are typically found in newer Audi models. If your car has an MMI 3G system, only compatible 3G updates are suitable.
