When a Go To, TracBack, or route has been activated, the GPSMAP 178C' s Highway Page provides
digital and graphic steering guidance to the destination. The top half of the Highway Page features
user-selectable data fi elds that display useful navigation data. The bottom section of the screen provides
visual guidance to the waypoint on a graphic highway display. The line down the center of the highway
represents your desired track line.
As you head toward your destination, the highway perspective moves to indicate your progress to
the waypoint and which direction you should steer to stay on course. If you are navigating a route, the
Highway Page shows each route waypoint in sequence connected by a red "road" with a yellow line
down the middle, which is your desired track line. Nearby waypoints not in the active route can also
be displayed. The highway perspective scale may also be zoomed in or out to display a larger or smaller
view of the highway. Five settings are available from 1X to 16X, with a default setting of 8X.
To change the highway perspective scale:
1. Press the ZOOM IN or ZOOM OUT key to select the desired setting.
The Highway Page options menu provides access to functions and features relating to the Highway
Page and the layout options. The data window, located at the top of the page, provides a user-selectable
layout of various types of useful data. Each data fi eld may be confi gured to display several data options.
The data window layout may also be changed to display additional data fi elds and change the actual
size of the data displayed.
