Disabling and Enabling Map Layers on the GPSMAP 67 Series
The GPSMAP® 67 and GPSMAP® 67i allow you to select which map layers are displayed so you can easily enable or disable any installed satellite imagery, PLSS (Public Land Survey System), USGS Quads, etc.
Disabling other layers can help give a better view of the other mapping information. Depending on the zoom level the map is being viewed at, certain layers may appear to be hidden if multiple layers are enabled.
