Larger Maps on Garmin Connect

When viewing an activity on Garmin Connect, the map has a fixed height. Especially on larger screens, you may want to view a larger map, but there is no built-in option to resize the map.

Using this bookmarklet, you can view the map in the full browser window.

  1. Drag the link below to the bookmarks bar:
    Connect Map
  2. Open an activity with a map on Garmin Connect;
  3. Click on the bookmarklet, the maps shows in the full window;
  4. Click again to restore the original size.

You may have to zoom in and out (Ctrl+, Ctrl-) to trigger the map to adapt to the new size.

The bookmarklet runs this JavaScript code:

    var e = document.getElementById('activity-map-canvas');
    if (!e) {
        alert('No map element found');
    if ( === 'relative') { = 'fixed'; = 0; = 0; = 0; ='100%'; = 100;
    } else {'400px'; = 'relative'
