Configuring the Chartplotter
Use the Configure screen to configure unit settings.
Configuring System Settings
To change general system settings from the Home screen, select Configure
> System.
Simulator—turn Simulator mode on or off. Select Setup to set simulator
options, such as simulated position, speed, and direction.
beeper/display—select beeper to set when the unit makes audible sounds.
Select display > backlight to brighten or darken the backlight. Select display
> Color Mode to switch between Day mode and Night mode ( page 4 ).
auto Power—turn Auto Power On or Off. When On is selected, the
chartplotter will automatically turn on whenever power is applied, unless the
chartplotter is turned off with the Power Key before power is lost.
• gPS—view GPS satellites.
• Skyview—view the GPS satellite constellation.
• waaS/EgNOS—toggle WAAS (in North America) or EGNOS (in
Europe) on or off. WAAS/EGNOS can provide more-accurate GPS position
information. However, when using WAAS or EGNOS, the device takes
longer to acquire satellites.
• Speed filter—select On, Off, or auto. The speed filter averages the speed
of your boat over a short period of time for smoother speed values.
• System information—view system information and reset factory settings
( page 6 ). The garmin devices > Save to Card option is provided as a
troubleshooting tool. A Garmin Product Support representative may ask
you to use this feature to retrieve data about your chartplotter.
Event Log—displays a list of system events. Select an event to view additional
information.
Configuring Units of Measure
To change units of measure from the Home screen, select Configure >
Preferences > Units.
System Units—a global setting that defines individual units of measure at
the same time: Statute (mh, ft, ºf), Metric (kh, m, ºC), Nautical (kt, ft, ºf),
or Custom. Select Custom to individually define units of measure for depth,
temperature, distance, speed, elevation, volume, and pressure.
NOTE: You must be receiving NMEA sonar depth data or have a built-in
sonar with a temperature-capable transducer to view depth and water
temperature information.
Heading—sets the reference used in calculating heading information.
• auto Magnetic—automatically sets the magnetic declination for your
location.
• True—sets true north as the heading reference.
• grid—sets grid north as the heading reference (000º).
• User Magnetic—allows you to set the magnetic variation value.
Position format—change the coordinate style in which a given location
reading appears. Do not change the position format unless you are using a map
or chart that specifies a different position format.
