The device works well with a free garmin program called base camp. You can pin point coordinates as a pin or wave point and upload that to the device via the usb cable provided. If you want to trace known trail routes in national parks for example I use the website Gaiagps.com. You can log in with Facebook and then save your traces routes as a gpx file then drag them to the device through base camp. Check out YouTube on how to use it, that’s where I learned. Hope that helps
