Using Map Page Features
Use the Zoom In and Out buttons to change the map scale in order to
show more map area with less detail or less map area with more detail.
Press and hold to Zoom the map scale rapidly.
The map scale in the lower left hand side of the display is shown in
units of measurement selected in the “Units” fi eld of the Unit Setup Page
(not to be confused with the Map Setup Page). If you zoom in so far that
the resolution of the map data is exceeded and the appearance of the map
is no longer accurate, the word, “ overzoom” displays just below the map
scale. When using MapSource detailed maps, “mapsource” appears below
the scale.
In many instances the map displays an “Accuracy Circle” surround-
ing the “Position Icon”. The GPSmap 76C uses both map resolution and
GPS accuracy in defi ning your location to a point within the circle. The
smaller the circle, the more accurate your location.
When using the “Pan Map” feature, a small outline arrow (Panning
Arrow) can be moved about the page to highlight and identify map items
or to scroll the map to view areas not shown on the display screen. If
there are more than one map items under the Panning Arrow. a list of
those items displays with the item highlighted on the map, also high-
lighted on the list.
Optional data fi elds can be added at the top of the display to provide a
variety of travel and navigational information, see pages that follow.
When navigating, Guidance Text will be displayed at the top of the map.
