Changing the Map Orientation on a Garmin Chartplotter
Garmin marine chartplotters and sounders have the ability to change the way the map is viewed. This setting is called Orientation. This setting has three different choices:
North Up - This option sets the top of the map to a north heading.
Head Up (Track Up) - This option sets the top of the map according to the heading data received from a heading sensor, also known as the magnetic heading, or to use GPS heading data. The heading line appears vertically on the screen.
Course Up - This option will set the map so the direction of navigation is always up. If a Go-To or Route To is enabled, the screen will show the direction of travel needed to get to the destination at the top of the screen. If no navigation is enabled, the map will be displayed with the direction the boat is traveling in at the top of the screen.
