[Align compass to GPS]
(1)
Follow the onscreen instructions to align your compass
with your GPS heading.
If your system has a GPS connected to your data
network (SeaTalk, SeaTalkng or NMEA), the autopilot
is tuned to the GPS heading while you steer to a
known magnetic heading. This step provides a rough
alignment and minimizes the amount of compass fine
tuning required. As part of the align to GPS process, the
autopilot system will compare the average heading with
the average COG (Course Over Ground) value reported
by the source of GPS data, and set an offset value so
that the heading matches the COG value provided by
the GPS.
