The GPSMAP 182/182C/232’s Map Page provides a comprehensive display of electronic car-
tography, plotting and navigational data. When using the unit with the optional BlueChart data or
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. An on-screen cursor lets you pan and scroll to other map areas, deter-
mine the distance and bearing to a position, and perform various route and waypoint functions.
When the cursor is active, an additional data window will appear below the data fi elds to indicate
the position, range and bearing to the cursor or a selected waypoint or map item. The map scale
displays at the bottom right of the page.
The (ZOOM) IN and (ZOOM) OUT keys, combined with the ARROW KEYPAD, let you select
zoom ranges and move the cursor. Two basic map operating modes, position mode and cursor mode,
determine what cartography is shown on the map display. Position mode pans the cartography to keep
the present position marker within the display area, while cursor mode pans the cartography to keep
the cursor within the display area.
The GPSMAP system will always power up in the position mode, with your vessel centered on
the map display.
• When suffi cient map coverage is not available to keep the boat centered, the boat icon will move
toward the edge of the display.
When the ARROW KEYPAD is pressed, the GPSMAP 182/182C/232 will enter cursor mode. In
cursor mode:
• The cursor can be moved over the map display using the ARROW KEYPAD.
• Whenever the cursor reaches the edge of the display, the map will scroll forward under the cursor.
Keep in mind that the boat icon will move with the map scrolling and may go off the display
screen (you may not be able to see your present position).
