With Topo Maps+ PRO you can add latitude/longitude or UTM grid overlays on your map.
To turn on the grid overlays select the overlays button and then grid overlays.
When you toggle on the Latitude/Longitude grid you will see grid lines that overlay the map that show you latitude and longitude.
You can customize the color and transparency of the grid lines.
You can also toggle on a UTM grid. When you zoom out you will see the grid zones and when you zoom in, you will see the northing and easting along the grid lines.
