Charts and 3D Chart Views Selecting the Heading Line Source 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. 1. From the Home screen, select Charts . 2.
