The course is automatically set so that the boat sails on the intended course line.
When the [NAV] key is pressed, the course changes automatically in order to
follow the intended course line. The course reading on the NAVpilot-500 is not
always equal to the waypoint direction which is presented on the plotter.
When you intend to navigate following a route, the boat goes to the second
waypoint in the route. Select the nearest or desired waypoint before going into
the NAV mode.
