Map Overlays

Topo Maps+ includes a variety of maps. Some cover the globe; others cover only a specific country or area, such as the US Forest Service map. These partial-coverage maps work best as an overlay, so you still have a base map underneath where their coverage runs out.

How to add a map overlay

  1. Tap the Maps button in the toolbar.

How to customize the Maps screen

You can hide the sections of the Maps screen you don't use and put the ones you use most at the top.

  1. Scroll to the bottom of the Maps screen and tap Customize Map Sections.
  2. Tap the eye icon next to a section to show or hide it. Drag a section to move it up or down. Base Map and Map Style always stay at the top.
  3. Tap Done.

To go back to the original layout, open Customize Map Sections, tap Restore Defaults, and confirm.

Trails overlay

Some maps show trails as part of the map image itself. You can see them, but you can't select them or use them with on-trail tools. To learn what those lines mean, check the map legend.

Selectable trails come from a trail overlay (OpenStreetMap trails or US Forest Service). You can save and download them, and they work with on-trail tools, much like a pre-drawn route.

  1. Tap the Maps button, scroll down to the Legacy section, and turn on Trails.
