Conguring Speed Data Sources
You can specify the source of the speed data that is used to calculate true wind speed or fuel
economy. Water speed is the speed reading from a water-speed sensor, and GPS speed is calculated
from your GPS position.
1. From the Home screen, select
Congure > System > Speed Sources.
2. Complete an action:
Select Wind, and indicate if the calculated wind speed data comes from a Water Speed
sensor, if it is based on the GPS Speed, or whether the chartplotter selects a speed data source
automatically.
Select Fuel Economy, and indicate whether the speed data that is used to calculate fuel
economy comes from a Water Speed sensor or it is based on the GPS Speed.
Auto Guidance Line Congurations
You can set the parameters the chartplotter uses when calculating an Auto Guidance line.
NOTE
: Auto Guidance is available with a preprogrammed BlueChart g2 Vision data card.
Safe Water Depth and Safe Obstacle Height
 CAUTION
The Safe Depth and Safe Height settings inuence how the chartplotter calculates an Auto
Guidance line. If an area has an unknown water depth or an unknown obstacle height, the Auto
Guidance line is not calculated in that area. If an area at the beginning or the end of an Auto
Guidance line is shallower than the safe water depth or lower than the safe obstacle height, the Auto
Guidance line is not calculated in that area. On the chart, the course through those areas appears as a
gray line. When your boat enters one of those areas, a warning message appears.
Setting the Safe Water Depth and the Safe Obstacle Height
1. From the Home screen, select Congure > Navigation > Auto Guidance.
2. Select
Safe Depth to set the minimum depth (chart depth datum) the chartplotter uses when
calculating an Auto Guidance line.
3. Enter the minimum safe depth.
4. Select
Done.
5. Select
Safe Height to set the minimum height (chart height datum) of a bridge that your boat can
safely travel under.
6. Enter the minimum safe height.
7. Select
Done.
Shoreline Distance Auto Guidance Setting
The Shoreline Distance setting indicates how close to the shore you want the Auto Guidance line to
be placed. The Auto Guidance line may move if you change this setting while navigating.
