Using a GPX file – with a GPS Device
Most GPS devices designed for outdoor sports and navigation can both create and use GPX files. The great thing about the universal nature of a GPX file is that different brands of device, with different maps loaded can all use the same GPX file.
Use an existing GPX file by loading it on to the device. Check your manual for details, but this normally means connecting the device to your computer by USB cable or Bluetooth, then sending the file to the device. The new route will then appear in the saved routes list on the device, and when active you will be able to follow it. Basic devices without on-screen mapping will generally just show an arrow to point to the next ‘waypoint’ (usually the next turning or fork) while more advanced ones will display the route on a map as well.
