2.1. What You’ll Need

A computer with internet access
A compatible SD card reader
Your Mercedes Benz Garmin SD card
The Mercedes-Benz Download Manager (DLM) software

2.2. Downloading and Installing the Mercedes-Benz Download Manager (DLM)

The Mercedes-Benz Download Manager (DLM) is the official software tool used to update your Garmin navigation system. Follow these steps to download and install the software:

Visit the Mercedes-Benz Website: Go to the official Mercedes-Benz website and navigate to the “Navigation Updates” section.
Download the DLM Software: Locate the download link for the Mercedes-Benz Download Manager (DLM) and download the software to your computer.

This is a crucial step that tricks the system into thinking it’s within the initial 60-day update window.

Access Vehicle Settings: In your Mercedes Benz, navigate to the “Vehicle” settings in the Audio 20 menu.
Reset Settings: Select “Reset Settings” (not the Navigation menu). This will reset the Audio 20 system.

The download and installation process may take several hours, so ensure your computer remains connected to the internet and the SD card reader throughout the process.

2.8. Activating the Update

Sometimes, the new update may not activate on the first attempt. If this happens, try the following:

Click “Activate”: Click the “Activate” button in the DLM software a couple of times.
Restart DLM: If the update still doesn’t activate, restart the DLM software. It may notify you of a canceled update, which will then reinstall and activate automatically.
Eject the Card: Use Windows Explorer to “Eject” the card safely before removing it from the SD card reader. This prevents data corruption.

2.9. Verifying the Update in Your Car

After installing and activating the update, verify that the new maps are installed correctly in your car.

Insert the SD Card: Insert the SD card into your Mercedes Benz Garmin navigation system.
Access Navigation Settings: Go to the navigation settings menu.
