Updating a Garmin Fleet Device with Garmin Fleet Updater

Garmin Fleet Updater is computer software used to update maps and device software by downloading and installing the latest versions to your device. These updates are released by Garmin several times a year.

Map Updates - Map updates provide the latest changes to roads and locations on the map used by your navigation device. The map files are large because they contain detailed information. These take longer to install.

Software Updates - Software updates make changes to the operating system files. These smaller files usually download in a few minutes. Garmin Fleet Updater will alert you to reboot your device after a software update.

Current Map Version: 2026.10 (North America) as of February 12, 2025.

Garmin Fleet Updater is aimed at businesses with a large number of GPS units.
