This menu is for selecting a different base map layer. The default is satellite (Clarity). If a building is newly built and does not appear on the base map, the satellite (Latest) layer may have it. When operating in urban areas, the open street maps layer may be the best choice since it displays a clear building footprint, and the buildings are often displayed at an angle in satellite imagery.
This menu is for enabling manual check-ins. When this option is used, a check-in icon is displayed on the main map screen and the user can place a pin to manually correct their position. See the double check-ins section of the initialization article for more information.
