GPS Settings
Select Settings > System > GPS .
Skyview : Shows the relative position of GPS satellites in the
sky.
GLONASS : Turns on or off GLONASS data (Russia satellite
system). When the system is used in situations with poor sky
visibility, GLONASS data can be used in combination with
GPS to provide more accurate position information.
WAAS/EGNOS : Turns on or off WAAS data (in North America)
or EGNOS data (in Europe), which can provide more-
accurate GPS position information. When using WAAS or
EGNOS data, the device may take longer to acquire
satellites.
Galileo : Turns on or off Galileo data (European Union satellite
system). When the system is used in situations with poor sky
visibility, Galileo data can be used in combination with GPS
to provide more accurate position information.
Speed Filter : Averages the speed of your vessel over a short
period of time for smoother speed values.
Source : Allows you to select the preferred source for GPS data.
Station Settings
Select Settings > System > Station Information .

System Units : Sets the unit format for the device.
Variance : Sets the magnetic declination, the angle between
magnetic north and true north, for your present location.
North Reference : Sets the direction references used in
calculating heading information. True sets geographic north
as the north reference. Grid sets grid north as the north
reference (000º). Magnetic sets the magnetic north as the
north reference.
Position Format : Sets the position format in which a given
location reading appears. Do not change this setting unless
you are using a map or chart that specifies a different
position format.
Map Datum : Sets the coordinate system on which the map is
structured. Do not change this setting unless you are using a
map or chart that specifies a different map datum.

Navigation Settings
NOTE: Some settings and options require additional charts or
hardware.
Select
Settings > Preferences > Navigation .
Route Labels : Sets the type of labels shown with route turns on
the map.
Turn Transition : Adjusts how the chartplotter transitions to the
next turn or leg or the route. You can set the transition to be
based on time or distance before the turn. You can increase
the time or distance value to help improve the accuracy of the
autopilot when navigating a route or an Auto Guidance line
with many frequent turns or at higher speeds. For straighter
routes or slower speeds, lowering this value can improve
autopilot accuracy.
Speed Sources : Sets the source for the speed readings.
Auto Guidance : Sets the measurements for the Preferred
Depth, Vertical Clearance, and Shoreline Distance, when you
are using some premium maps.
Route Start : Selects a starting point for route navigation.
Auto Guidance Path Configurations
CAUTION
The Preferred Depth and Vertical Clearance settings influence
how the chartplotter calculates an Auto Guidance path. If an
area has an unknown water depth or an unknown obstacle
height, the Auto Guidance path is not calculated in that area. If
an area at the beginning or the end of an Auto Guidance path is
shallower than the Preferred Depth or lower than the Vertical
Clearance settings, the Auto Guidance path may not be
calculated in that area, depending on the map data. On the
chart, the course through those areas appears as a gray line or
a magenta and gray striped line. When your boat enters one of
those areas, a warning message appears.
