2021 Audi MMI Navigation Database Concerns TSB

Owners of 2021 Audi vehicles may encounter various issues with their MMI navigation systems, such as missing roads, incorrect speed limits, or outdated points of interest. Audi has issued Technical Service Bulletin (TSB) 91 20 70 2044694/2 to address these common MMI navigation database concerns.

This TSB outlines the potential causes for these discrepancies, which stem from the map database compilation and release process. It also provides detailed instructions for updating the navigation map database across different MMI system generations, aiming to resolve the Audi e-tron navigation database concerns and similar issues in other models.

Symptoms

If you own a 2021 Audi, you might experience one or more of these MMI navigation database concerns:

• Missing traffic info: Certain map sections do not display speed and flow traffic data.
• Missing streets: New streets are not shown on the navigation map.
• POI not listed: Specific points of interest (POIs) are absent from the navigation database.
• Incorrect speed limits: The speed limit displayed on the map is missing or inaccurate.

These issues can lead to frustration and impact the effectiveness of your vehicle's navigation system.

Fault Codes / DTCs

This Technical Service Bulletin does not list any specific Diagnostic Trouble Codes (DTCs) associated with these navigation database concerns. The issues are related to the map data itself rather than a fault in the vehicle's electronic systems that would trigger a DTC.

What the Service Bulletin Says

Technical Service Bulletin 91 20 70 2044694/2, which supersedes TSB 16-55, explains that the navigation map database is provided by HERE maps. Due to the time required for data compilation, validation, and service part creation, the database can be nearly a year old by the time it's released.

To mitigate this delay, Audi has implemented various update methods depending on the MMI system version:

• MIB2, MIB2+, and MIB3 systems: Customers can update their navigation map database using Over-the-Air (OTA) updates directly through the MMI. MIB2 systems offer three free USA regional updates for the first three years, while MIB2+ and MIB3 receive incremental updates quarterly or monthly based on driving habits.
• MIB1 systems: Owners need to download the database from myAudi to an SD card and then manually update it via the MMI's SD card slot.
• MMI3G+ systems: Before installing the latest navigation map database, customers must update their system software to ZUG K0814 or higher (ZUG K0942 was the latest as of calendar week 22/17).
• MMI 2G and RNS-E systems: These systems do not require activation documentation for map updates.

For some MIB1 and MIB2 systems, or vehicles older than three years, an activation document may need to be purchased to install the latest map database. Additional information can be found in TSB 2037809, which details how to update MMI MIB navigation maps and addresses potential customer concerns.

What to Do

If you are experiencing Audi e-tron navigation database concerns or similar issues in your 2021 Audi, the recommended course of action is to update your MMI navigation map database. For MIB2, MIB2+, and MIB3 systems, check for Over-the-Air updates through your MMI interface. MIB1 owners should visit the myAudi portal to download the latest map data to an SD card for manual installation.

Owners of MMI3G+ systems should ensure their system software is updated to ZUG K0814 or a newer version before attempting a map update. If you are unsure about the process or your specific MMI system, it is best to consult your authorized Audi service center. They can assist with identifying your MMI version, performing necessary software updates, and installing the latest navigation map database.
