Time—set the time options.
• Time Format—select 12-hour, 24-hour, or
• Time Zone—set the time zone displayed for time readings.
• Daylight Saving Time—select Off, On, or Auto. The Auto setting automatically turns daylight
saving time on or off, depending on the time of year.

Configuring Communications Settings

From the Home screen, select
NMEA 0183 Setup—enable or disable NMEA 0183 output sentences for sounder, route, system,
and Garmin NMEA settings.
• Port Types—configure the input/output format for each port to use when connecting your
chartplotter to external NMEA devices, a computer, or other Garmin devices. NMEa Std.
supports the input or output of standard NMEA 0183 data, DSC, and sonar NMEA input support
for the DPT, MTW, and VHW sentences. NMEA High Speed supports the input or output of
standard 0183 data for most AIS receivers. The Garmin option supports the input or output of
Garmin-proprietary data for interfacing with Garmin software.
• Output Sentences—configure how the device sees NMEA 0183 output sentences. See
for information on configuring these sentences.
• Posn. Precision—adjust the number of digits (Two Digits, Three Digits, or Four Digits) to the
right of the decimal point for transmission of NMEA output.
• Waypoint IDs—determine how the device outputs waypoint identifiers (Names or Numbers).
• Defaults—reset NMEA 0183 settings to their default settings.
• Diagnostics—a tool used by installers to verify that NMEA 0183 data is being sent across the
system.
NMEA 2000 Setup—View and configure the devices connected to the NMEA 2000 network and set
bridging to On, Off, or Auto.
• Device List—lists the NMEA 2000 devices on your network. If a NMEA 2000 device has
configuration options or settings, select the device for a list of options.
• Output Bridging—Output bridging occurs when a chartplotter takes NMEA 0183 data it
receives from any source, formats it into NMEA 2000 data, and then sends it over the NMEA
On
2000 bus. Select
to allow the chartplotters on the network to negotiate with each other to determine which
chartplotter will perform this function. Only one chartplotter on the network will bridge NMEA
0183 data over the NMEA 2000 bus at a time.
Wireless Devices—Allow wireless devices, such as a remote control or optical mouse to
communicate with the chartplotter.
Preferred Sources—Assign a preferred device when more than one source is available for the same
function.
Marine Network—Review all connected Garmin Marine Network devices
