If you are going to interface the GPSMAP 176/176C with another 

piece of equipment (such as a radar or autopilot), the unit needs to 

be set to output NMEA data. The NMEA data can be customized to 

shorten the update time from the unit. If too many NMEA sentences 

are activated, the unit may take longer than two seconds to update. 

1.  With the GPSMAP 176/176C turned on, press 

MENU twice to 

display the Main Menu. Use the 

to select the Setup-

Interface tab.

2.  Highlight the 

Serial Data Format field and press ENTER.

3.  Select 

NMEA In/NMEA Out and press ENTER. 

The GPSMAP 176/176C NMEA data transmission can be customized 

to keep the output rate at two seconds. If the unit is set up to output 

all of the available NMEA sentences, the output rate may exceed 

two seconds. The Advanced NMEA Output Setup page allows you 

to turn on/off the GPS status (GSA, GSV), Waypoint/Route (WPL, 

RTE), and the Garmin Proprietary sentences. You can also change the 

precision of the Lat/Lon minutes.

1.  With 

NMEA In/NMEA Out selected, press MENU. Select 

Advanced NMEA Setup and press ENTER.

2.  To turn a field On/Off, highlight the desired field and press 

ENTER. Make a selection and press ENTER again.
