coordinates entered manually (not through the
map) are based on the map datum selected by the
user through the Aux function.

Selecting Map Orientation
When navigating on the map, there are two methods of ori-
enting the map and the boat icon.
When Map Orientation is set to North Up,
the boat icon rotates according to its COG
direction, with respect to north; the map does
not rotate.
When Map Orientation is set to Track-Up, the boat icon al-
ways points up while the map rotates so the top of the screen
is always the COG direction. The map rotates every time
COG changes more than the specified number of degrees set.
Press the Aux softkey, highlight Navigation Setup using
the CURSOR KEY, press ENTER, highlight Map Orien-
tation using the CURSOR KEY, and press ENTER. Use
the CURSOR KEY to highlight North Up or Track Up
and press ENTER to accept. If Track Up is selected, the
resolution of rotation must be entered (the default is 10°).
