Compass Page - Garmin GPSMAP 178C Owner's Manual

Compass Page

The GPSMAP 178C Sounder features two different navigation pages: Compass and Highway. When-
ever a NAV goto, Follow Track (TracBack), or Follow Route have been activated, the GPSMAP 178C
Sounder' s Compass Page guides you to your destination with digital readouts and a graphic compass
display, which includes a bearing pointer. Use this page (instead of the Highway Page) when your desired
path may be varied in direction . The middle of the page features a rotating 'compass ring' that shows your
course over ground (track) while you're moving. Your present course over ground is indicated at the top
of the compass ring. A bearing pointer arrow, in the middle of the compass ring, and a bearing 'bug' indi-
cator on the outside of the compass ring, indicate the direction of the destination (bearing) relative to the
course over ground. The compass ring and pointer arrow work independently to show—at a glance—the
direction of your movement and the direction to your destination. For instance, if the arrow points up,
you are going directly to the waypoint. If the arrow points any direction other than up, turn toward the
arrow until it points up, then continue in that direction.
The bearing pointer, bearing bug and/or compass ring may point in various directions
when you are stationary or at very low speeds. Once you start moving, the pointer is
correct.
The GPSMAP 178C' s Compass Page features a menu page that provides access to layout and data
fi eld options. The data window, located at the top of the page, provides a user-selectable layout of vari-
ous types of useful data. Each data fi eld may be confi gured to display several data options.
To display the Compass Page options:
1. Press MENU.
To select a menu option:
1. Use the ARROW KEYPAD to highlight the desired option and press ENTER.
For detailed instructions on changing data fi elds and layout of the Compass Page, see pages 29-31.
