Garmin Edge cycling computers are invaluable tools for many cyclists, providing navigation and tracking features. While Garmin offers its base maps installed on your device, many people will need to install additional maps if they are traveling. The most convenient way to do this is to use OpenStreetMap (OSM). OSM provides free, regularly updated, community-driven maps. Here’s a step-by-step guide on how to install OSM maps onto your Garmin Edge device.
