Garmin Express will display the updates. Your device may have a software update available, a map update available, or both. You will have an option to “Update Software,” “Update Maps,” “Install,” or “Install All.” Each path begins with this selection.

NOTE: Your device may require a software update before installing a new map. In this case, the software update will be installed before returning you to this screen where you will then have the option to “Install All” or “Update Maps.”

4. Click Update Software, Update Maps, Install, or Install All

Clicking View Details allows you to see a list of available updates and install them individually.

Garmin recommends clicking the option in the blue button to ensure all updates are installed.

  • Only compatible with the RV 780, RV 785, RV 890, RV 1090, and zūmo® XT GPS navigators.

9. Read the notes and click Continue

Garmin Express will display the Map Update progress.

An “Updates complete” message will appear when the map update finishes.

Note: Disconnecting the device or shutting down the computer before the update completes will cause an error and may make the device unusable.

Use a Memory Card (Recommended) - In situations where a Garmin device does not have sufficient internal storage space to load the full coverage of a City Navigator NT map update, Garmin Express allows the maps to be installed to a microSD/SD card. 

When using the SD card installation option, critical files are loaded to the SD card so it must remain in the device after the update to ensure full functionality. For the largest size SD card a device can use, see the FAQ SD Memory Card Sizes for Automotive Devices.

Adding a memory card to a compatible device will help to give it enough storage space for the entire map. For more information about using a memory card for map updates, including SD card size requirements and instructions if Garmin Express does not offer a memory card option, see Garmin Express Prompts to "Use A Memory Card (Recommended)".

If you select Use a Memory Card, the card must be inserted into the device, not the computer. The map file will be deleted from the device's internal storage drive; therefore, the memory card must remain inside the device at all times both during and after the map update.

NOTE: Voice Command requires the full map to work.

If issues persist, see Garmin Express Only Offers Options to Contact Product Support or Use a Memory Card for additional steps.
