Charts and 3D Chart Views

The source for the display of the heading line on the chartplotter is determined by the heading line source 

setting (Auto or GPS Hdg) and whether heading information is available from a heading sensor.
•  If heading information is available from a heading sensor and the source heading is set to Auto, both the 

heading line and the vehicle icon will be aligned to the heading from the sensor.

•  If heading information is available from a heading sensor and the source heading is set to GPS Hdg, the 

heading line will be aligned to the GPS heading, but the vehicle icon will be aligned to the heading from 

the sensor.

•  If heading information is not available from a heading sensor, both the heading line and the vehicle icon 

will be aligned to the GPS heading.
