Map and Software Updates
For the best navigation experience, you should keep the maps and software on your device up to date.
Map updates provide the newest available changes to roads and locations in the maps used by your device. Keeping maps up to date helps your device find recently added locations and calculate more accurate routes. Map updates are large and may take several hours to complete.
Software updates provide changes and improvements to the device features and operation. Software updates are small and take a few minutes to complete.
You can update your device using two methods.
You can connect the device to a Wi‑Fi® network to update directly on the device (recommended). This option allows you to update your device conveniently without connecting it to a computer.
You can connect the device to a computer and update it using the Garmin Express™ application (garmin.com/express). This option allows you to install map data onto a memory card if the updated maps are too large to fit on the internal storage.
