Map Page Zoom Scale Bearing to Waypoint Track Over Ground Pan & Configure Fields Distance to Waypoint Present Position Speed Over Ground The Map Page shows your position and surroundings, and provides you with a target cursor that lets you pan ahead to determine the distance and bearing to a map position, mark new waypoints and goto waypoints while you navigate. The Map Page is broken down into two sections: control fields and map section. The zoom function, panning control, and configuration fields are located at the top of the screen. The zoom function uses 12 selectable zoom ranges from 0.2 to 320 miles or 0.5 to 600 km. (Using the zoom, panning, and configure fields will be addressed in the next section.) The map portion of the page displays your present position as a diamond icon, your track and/or route as a solid line, marine database points (see page 20), and waypoints by squares or the selected symbol, the waypoint name or comment may also be displayed. Range Rings may be displayed to help estimate distances. You may select which of these features are shown through the map setup submenu page (see pg. 24 for more information). The four corners of the Map Page are used to display various navigation data, including the bearing and distance to a destination waypoint and your current track and speed over the ground. The two fields at the top corners of the map show your bearing and distance to one of three selectable destinations: an active destination waypoint, a highlighted on-screen waypoint, or the panning target crosshair. If you are not navigating to a waypoint or using the panning function, the top data fields will not be displayed. Your current track and speed are shown at the bottom corners of the display. REFERENCE Map Page Note: A map scale represents the distance shown from the bottom to the top of the Map Page. For example, when viewing the 10 mile scale, the distance represented between the top of the screen and bottom is 10 miles. The four corners of the Map Page are used to show your course, speed, and distance to either a cursor or to a destination waypoint. 19
