Map Page
The Map Page provides a comprehensive display of electronic
cartography, plotting, and navigational data. When in the BlueChart
data coverage area or using optional MapSource software, the
map display shows your boat on a digital chart, complete with
geographic names, map items, navaids, and a host of other chart
features. It also plots your track and displays any routes and
waypoints you create. A map pointer allows you pan and scroll to
other map areas, determine the distance and bearing to a location,
and perform various route and waypoint functions.
When the pointer is active, an additional data window appears
below the data fields to indicate the location, range, and bearing
to the pointer, a selected waypoint, or map item. The map scale
displays at the bottom right of the page.
The Zoom IN and OUT keys combined with the ROCKER, allow
you select zoom ranges and move the pointer. Two basic map
operating modes, Position Mode and Pointer Mode, determine what
cartography is shown on the map display. Position Mode moves the
cartography to keep the present position marker within the display
area. Pan Mode moves the cartography to keep the map pointer
within the display area.

The GPSMAP 182/182C system starts in the Position Mode,
with your location centered on the map display. When sufficient
map coverage is not available to keep your location centered, the
position triangle moves toward the edge of the display.
Pan Mode starts when the ROCKER is pressed. The pointer
is moved over the map display using the ROCKER. When the
pointer reaches the edge of the display, the map scrolls forward
under the pointer.
