Garmin Explore
The Garmin Explore™ website and app allow you to plan trips and use cloud storage for your waypoints, courses, and collections. They offer advanced planning both online and offline, allowing you to share and sync data with your compatible Garmin® device. You can use the app to download maps for offline access, and then navigate anywhere without using your cellular service.
You can download the Garmin Explore app from the app store on your phone, or you can go to explore.garmin.com.
