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).
Updating Maps and Software Using a Wi‑Fi Network
Map and software updates may require the device to download
large files. Regular data limits or charges from your internet
service provider apply. Contact your internet service provider for
more information about data limits or charges.
You can update the maps and software by connecting your
device to a Wi‑Fi network that provides access to the internet.
This allows you to keep your device up to date without
connecting it to a computer. Verify your vehicle is parked in a
safe location and consistent power is supplied to the device
during the update process.
