REFERENCE
Map Page
Note: A map scale repre-
sents the distance shown
from the bottom to the top
of the Map Page. For
example, when viewing
the 10 mile scale, the dis-
tance represented between
the top of the screen and
bottom is 10 miles.
The four corners of the
Map Page are used to
show your course, speed,
and distance to either a
cursor or to a destination
waypoint.
Map Page
The Map Page shows your position and surroundings,
and provides you with a target cursor that lets you pan
ahead to determine the distance and bearing to a map
position, mark new waypoints and goto waypoints while
you navigate. The Map Page is broken down into two
sections: control fields and map section.
The zoom function, panning control, and configura-
tion fields are located at the top of the screen. The zoom
function uses 12 selectable zoom ranges from 0.2 to 320
miles or 0.5 to 600 km. (Using the zoom, panning, and
configure fields will be addressed in the next section.)
The map portion of the page displays your present
position as a diamond icon, your track and/or route as a
solid line, marine database points (see page 20), and
waypoints by squares or the selected symbol, the way-
point name or comment may also be displayed. Range
Rings may be displayed to help estimate distances. You
may select which of these features are shown through the
map setup submenu page (see pg. 24 for more informa-
tion).
The four corners of the Map Page are used to display
various navigation data, including the bearing and dis-
tance to a destination waypoint and your current track
and speed over the ground. The two fields at the top
corners of the map show your bearing and distance to
one of three selectable destinations: an active destination
waypoint, a highlighted on-screen waypoint, or the pan-
ning target crosshair. If you are not navigating to a way-
point or using the panning function, the top data fields
will not be displayed. Your current track and speed are
shown at the bottom corners of the display.
