providing position data):

The navigator creates a new temporary waypoint called
COORD
and returns to the
SOUNDTRAC
screen. The
COORD
waypoint isn’t stored in the waypoint database;
instead, it’s placed in the trip, where it replaces any future
trip points. To see this current waypoint on the
CHART
screen, press
CHART
at any time. Your present vessel
position and time have now become a past trip point.
