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  > >  > .
2. Complete an action:
• Select , and indicate whether the calculated wind speed data comes from a  sensor, if
it is based on the , or whether the chartplotter selects a speed data source automatically.
• Select , and indicate whether the speed data that is used to calculate fuel economy
comes from a  sensor or if it is based on the .
Auto Guidance Line Congurations
You can set the data the chartplotter uses when calculating an Auto Guidance line.
: 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 message
appears.
Setting the Safe Water Depth and the Safe Obstacle Height
1. From the Home screen, select  >  >  > .
2. Select  to set the minimum depth (chart depth datum) the chartplotter uses when calculating an
