Allow this map source to be used for offline downloads.

Tap ‘Done’ to return to the maps list. Tap on the ‘+’ button and select ‘Offline map’.

Give your offline map a name (1) and tap on the map source row (2).

Pick the Open Street Map source and confirm by tapping ‘Done’.

On the offline map screen, pick the map region to download (1) and zoom levels to download (2 — 2 to 16 is a good default choice). Start the map download (3) and wait until it finishes.

Tap ‘Done’ and select the newly downloaded map in the map list.

Confirm by ‘Done’ and review your offline map on the main map.

If you don’t see the map, use the button with the map name (1) to focus on the map region on the main map.

The main map will show the downloaded map region (1) and you can use zoom buttons (2) or fingers to zoom into it.

If you don’t see the zoom buttons (2), tap on the map and they will appear briefly.
For regions that are not downloaded, the map shows gray squares.
This should be it! If the map is not following your location after all that, don’t forget to use the ‘RE-CENTER’ button (1), so map follows your location again.
