Garmin gpsmap 178, 178c Manuale Utente

The GPSMAP 178/178C Sounder features two different navigation pages: Compass and Highway. 

Whenever a NAV goto, Follow Track (TracBack), or Follow Route have been activated, the GPSMAP 

178/178C 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’ 

indicator 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 bearng ponter, bearng bug and/or compass rng may pont n varous drectons 
when you are statonary or at very low speeds. Once you start movng, the ponter s 
correct.

The GPSMAP 178/178C’s Compass Page features a menu page that provides access to layout and data 

field options. The data window, located at the top of the page, provides a user-selectable layout of various 
types of useful data. Each data field may be configured to display several data options. 

1.   Press MENU . 

1.   Use the ARROW KEYPAD to highlight the desired option and press ENTER . 

For detailed instructions on changing data fields and layout of the Compass Page, see pages 29-31.
