Using Non-Garmin/Third-Party Maps or Software with an Overlander

Garmin automotive devices are meant to be used with Garmin-provided maps. These can be purchased at garmin.com/maps. To check compatibility with your device, select the map you wish to purchase and click on Compatible Devices.

The Overlander® GPS navigator can use the Garmin Explore™ App to download multiple mapping options as well as create and manage waypoints, routes, and other data. For more information, see Topographic Map Coverage for the Overlander & Creating Waypoints and Routes in the Garmin Explore App. 

NOTES:

• .IMG files must be located in a "Map" folder on the microSD card and/or the device for your device to display them.

• Garmin cannot provide support or guarantee compatibility for map products or software purchased from other companies. Garmin cannot cover the device under warranty if it becomes unusable as a result of using third-party maps or software.

• For support of third-party map products or software, including setup, usage, and error messages, contact the manufacturer of the map or software program.

• You may have to disable some Garmin maps for the third-party map to show on the map page of the device. Ensure the Basemap is also enabled.
