2020-2026 Audi MIB3 Navigation: Addresses & Favorites Deleted

Audi has issued Technical Service Bulletin (TSB) 2077148/2 to address a recurring problem affecting the MIB3 navigation system in various 2020-2026 Audi models. Owners may find that their saved navigation data, including home addresses, work addresses, last destinations, and favorites, are intermittently deleted. This bulletin provides insight into the cause of the issue and offers a recommendation to help prevent the loss of your important navigation entries.

Symptoms of Deleted Navigation Data

Owners experiencing this issue will notice that their previously saved navigation entries are no longer present in the MIB3 system. Specifically, the following symptoms indicate that your Audi MIB3 navigation deleted data:

• Deleted Addresses and Favorites: Saved home addresses, work addresses, last destinations, and favorite locations disappear from the MMI navigation system.
• Restricted AC Display Shortcuts: If your vehicle is equipped with a separate air conditioning display, the functionality of its shortcuts may become restricted when the complaint occurs.
• myAudi App Discrepancy: Destinations that were previously shown in the myAudi app may no longer appear, indicating a loss of synchronization with the vehicle's system.

This issue can occur irregularly and may be difficult for technicians to reproduce consistently in a workshop setting. The core problem is that saved destinations are not retained after the system is restarted.

Technical Background of the Issue

In the Audi MMI navigation system, there's a distinction between two types of destinations:

• Standard destinations: These are saved directly within the Audi navigation database and are considered offline entries.
• Google destinations: These are provided by Google and are online entries. They can be sent to the vehicle via the myAudi app (marked as “Places powered by Google”) or found using the Google destination search function on the MMI (identified by a star rating or the text "powered by Google").

The root cause of the Audi MIB3 navigation deleted data is synchronization discrepancies between Audi and Google servers, which primarily affect Google destinations saved in the MMI. When these discrepancies occur, the system may lose the saved Google-sourced entries.

Important Warnings for Owners

Audi recommends that owners primarily save standard destinations manually by entering them directly into the MMI without activating the Google search function (the "G" icon). This approach helps to avoid the synchronization issues that lead to the loss of Google destinations.

It is important to note that Technical Service Bulletin 2077148/2 is informational only and is not applicable to any Audi Warranty. This means that any diagnostic or service work related to this specific issue may not be covered under your vehicle's warranty.

Owner Action

If you are experiencing issues with your Audi MIB3 navigation deleted addresses and favorites, it is advisable to visit your authorized Audi dealer. While the TSB is informational, your dealer can explain the situation in detail and guide you on how to save destinations to minimize the risk of loss. Following the recommendation to save only standard destinations manually is the primary action owners can take to mitigate this problem.
