Map Page The Map Page provides a comprehensive display of electronic cartography, plotting, and navigational data. When using the unit with optional BlueChart or MapSource data, the Map Page 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 shows any routes and waypoints you create. The 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 map pointer is active, an additional data window appears at the top of the map to indicate the location, range, and bearing to the map pointer, a selected waypoint, or map item. The map zoom range shown at the lower-right corner of the Map. The Zoom RANGE Down and RANGE Up keys combined with the ROCKER, allow you select zoom ranges and move the map pointer. Two basic map operating modes, Position Mode and Pan Mode, determine what cartography is shown on the Map Page. Position Mode moves the cartography to keep the present position marker within the screen area. Pan Mode moves the cartography to keep the map pointer within the screen area. MAIN PAGES > MAP PAGE The GPSMAP 392/398/492/498 starts in Position Mode, with your location centered on the Map Page. When sufficient map coverage is not available to keep your location centered, the position triangle moves toward the edge of the screen. Pan Mode starts when the ROCKER is pressed. The map pointer is moved over the Map Page using the ROCKER. When the map pointer reaches the edge of the screen, the map scrolls forward under the map pointer.
