Download and transfer maps to your watch

In the Flow web service, you can access the map download page by clicking your name/profile photo in the upper right corner and choosing Download maps. You can also use the direct link: flow.polar.com/maps.
You can download new maps or download the maps on your watch again to update them. You can choose maps that are smaller and more detailed, or larger and more basic.
- Detailed maps (Countries and regions) show for example smaller trails and contour lines.
- Basic maps (Continents and large areas) show for example main roads and tracks. Basic maps of North America and Europe are pre-installed on your watch.
When you click on a region on the map, you will see the size of the map and when it was last updated. To download the map, click on the Download button.
