Map Page
The Map Page screens show your course and track from a bird's-eye

view. By default, this unit shows the map with north always at the top
of the screen. (This can be changed. See the topic Map Orientation, in

Sec. 8.) If you're navigating to a waypoint, the map also shows your

starting location, present position, course line and destination. You,

however, don't have to navigate to a waypoint to use the map.
Map Page is the default screen that appears when you turn on the unit.

. When the Map Page is displayed, a screen similar to the fol-

lowing figures appears.
The arrow in the center of the screen is your present position. It points

in the direction you're traveling. The solid line extending from the back

of the arrow is your plot trail, or path you've taken.
The map zoom range is the distance across the screen. This number

shows in the lower right corner of the screen. In the first of the follow-

ing example figures, the range is 4,000 miles from the left edge of the

map to the right edge of the map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its

coverage area and the amount of mapping detail shown. There are 39

available map zoom ranges, from 0.02 miles to 4,000 miles.

Map Page opening screen (left). Set to 100-mile zoom (center) and 10-

mile zoom (right). Over Zoomed means you have reached the detail

limits in an area covered only by the basic background map. Zooming

in closer will reveal no more map detail because a high-detail custom

map has not been loaded on the MMC for this area.
