Map Page
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
