The GPSMAP 168 Sounder’s Map Page provides a comprehensive display of electronic cartography,

plotting and navigational data. When using the unit with the 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.
An on-screen cursor lets you pan and scroll to other map areas, determine 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 corner of the page.

The IN and 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.

• If the boat icon attempts to go off the display, the zoom level may need to be adjusted to keep

cartography on screen.
