Numbers Page
The Numbers Page provides a quick reference for the important data you want to display. The
default page displays three large, user-selectable data fi elds showing a compass ribbon, speed and cur-
rent position coordinates. You may also choose to show the three data fi elds in large lettering for better
readability or you may ‘split’ any or all of the data fi elds to show 4 smaller data fi elds. For detailed
instructions on changing the data fi elds and layout of the Numbers page, see pages 26-28.
Highway Page
When a Go To, TracBack, or route has been activated, the GPSMAP 188/188C/238 Sounder’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. Additionally, a
compass ribbon is displayed to show your current heading along with a dark, vertical bar indicates the
bearing to your course. To stay on course, steer towards the black vertical indicator (or arrows) until it
lines up with the red bar in the middle. 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.
