MarIne Mode PaGeS
Five pages are available in Marine Mode—Map, Compass,
Highway, Active Route, and Position Data. An optional Sonar
Page is available when a GSD 20 or GSD 21 Sounder Module is
connected.
Map Page
When you turn on the GPSMAP 276C, the Map Page appears after
the unit acquires a satellite signal. The position marker shows
your current location on the map.
The Map Page shows map information (digital cartography) that
includes navaids, lakes, rivers, coastlines, cities, and highways. Use
the dedicated zoom keys (IN and OUT) to adjust the Map Page
scale.
Two map operating modes, position mode and pan mode, determine
what cartography is shown on the map. Position mode pans the map
to keep your present location in the display area. The position marker
shows your travel on the Map Page. The GPSMAP 276C always
turns on in position mode, with the last known location centered on
the map. When you press the ROCKER, the GPSMAP 276C enters
pan mode, which moves the map to keep the white arrow (map
pointer) within the display area.
The system has a built-in worldwide database, with more detailed
coverage available through the use of the BlueChart g2 or
MapSource data. The GPSMAP 276C shows cartography as long as
chart information is available for the map zoom range you selected.
In Marine Mode, by default, four user-selectable data elds appear
on the right side of the screen that can be congured to show any
one of the possible data options. You can also add additional data
elds to the page or select a full screen map without data elds.
