Furuno GP-1850W - Manual (Page 3)

Four chart orientations are available in the course plot display:
True Motion North-up, Relative Motion North-up, Course-up and
and Auto Course-up modes. In the True Motion modes,
coastlines remain stationary on the screen while your vessel
moves according to its actual speed and course. In the Relative
Motion mode, your vessel is kept at the screen center and
coastlines move relative to your vessel.
The course plot display shows your vessel's position with a
motion trend vector, route, position, speed and course. Your
vessel's heading and speed are
indicated by a vector at your
present position. Display colors
can be changed for optimum
visibility depending on ambient
light conditions.
