2021 Mercedes-Benz AMG GT MBUX Navigation Update

Why This Matters

Mercedes-Benz has initiated a service campaign to update the MBUX control unit software in certain 2021 Mercedes-Benz AMG GT vehicles. The manufacturer, Mercedes-Benz AG (MBAG), determined that the software for the MBUX control unit in these vehicles might not align with the most recent series production configuration. This discrepancy can lead to the navigation system being unavailable, impacting driver convenience and potentially safety.

Approximately 38,293 vehicles across various Mercedes-Benz models from model years 2021-2022 are affected by this issue. This includes the A-Class (177 platform), CLA-Class (118 platform), CLS-Class (257 platform), E-Class (213 and 238 platform), GLA-Class, GLB-Class (247 platform), GLC-Class (253 platform), GLE-Class, GLS-Class (167 platform), and GT-Class (290 platform).

Symptoms

The primary symptom owners may experience is that the "navigation may not be available" within the MBUX multimedia system. This means the built-in navigation functions will not operate as expected, potentially leaving drivers without guidance or access to location-based services.

What's Being Done

Mercedes-Benz USA (MBUSA) is conducting a service campaign, identified as Campaign No. 2022010008 (also referenced by Campaign Desc. 21P5497301). Authorized Mercedes-Benz dealers will update the MBUX control unit software to ensure it matches the latest series production configuration. This update is expected to resolve the issue of unavailable navigation.

Repair Procedure Summary

The repair involves a software update to the multimedia system (MBUX) control unit. Technicians will perform the following steps:

1. Connect XENTRY Diagnosis: The vehicle's diagnostic system, XENTRY Diagnosis, must be connected. It is crucial to use version BD/DVD (12/2021) or higher and ensure all current add-ons are installed.
2. Update MBUX Control Unit Software: Within XENTRY Diagnosis, the technician will navigate to "Quick test view – A26/17 MBUX multimedia system (Head unit) – Adaptations – Control unit update - Updating of control unit software." They will then follow the user guidance provided by the diagnostic system to complete the software update.
3. Disconnect XENTRY Diagnosis: Once the update is successfully completed, the diagnostic system will be disconnected.

Throughout this process, a battery charger must be connected to maintain the vehicle's on-board electrical system battery above 12.5 V, preventing power interruptions during the software update.
