each waypoint and manually change the set course to equal the
bearing to the next waypoint and then select NAV mode again.

Press NAV to accept the first waypoint as the location to steer
towards. The autopilot turns the boat onto the new course while
the display flashes “TURNING”.
Accepting the first waypoint as the location to steer towards you
also accept the autopilot to automatically steer the boat through
the route of waypoints. When the autopilot changes the course at
each waypoint, the display flashes “TURNING”.
If you wish to confirm the new heading at each waypoint, GPS
has to be selected as NAV source.
A route consists of a series of waypoints joined together with
straight legs. Each waypoint in a route, except the first and the
last, has an associated turn radius defined. This turn radius will
allow the ship to turn before the waypoint is reached.
