3. STEERING MODE

3.3.2 Selecting sailing method of NAV mode
When your vessel goes off course while navigating between the origin (previous
waypoint) and your current destination waypoint because of a remote control
command, etc. the NAV mode uses one of two methods to get back on course:
COURSE or XTE. (See figure in below.) If COURSE is selected, the
NAVpilot-511/520 will calculate a new course based on your new position after
dodging, etc. that will take you directly to your destination waypoint. If XTE is
selected, the NAVpilot-511/520 will use XTE or cross track error to steer the boat
towards your ORIGINAL course before dodging. You may select, either
COURSE or XTE as shown below.
