Compass Page (continued)
The middle of the compass page features a rotating “com-
pass” which shows your current cardinal heading while you’re
moving (track up), with a pointer- a rrow in the center to indi-
cate the direction of the destination relative to the dire c t i o n
you are moving. The compass and pointer- a rrow work
together to provide a picture of the direction you are moving
and the direction of the destination at a glance.
The bottom of the compass page displays your curre n t
track (TRK) and speed (SPD) over the ground, while the CDI
(course deviation indicator) scale shows how far you are off
course. The diamond in the center of the CDI scale re p re s e n t s
your present position, while the d-bar (the moving vert i c a l
line on the scale) indicates the direction and distance you are
o ff the desired straight line course.
To stay on course, simply steer toward the d-bar until it is
c e n t e red on the position diamond. The default setting of the
CDI scale is +/- 0.25 miles, with each mark re p resenting 0.05
miles of course deviation. If you do get off course by more
than the selected scale, an arrow prompt will appear at the
end of the scale to indicate the direction you are off course.
For more information on setting the CDI scale, see page 47.
When you are one minute away from the destination
(based on current speed and track over the ground), the GPS
40 will alert you with a flashing on-screen message box.
To view a message:
1. Press the
P
key when the message box appears.
2. Press
P
again to return to the previous page.
When the DST field displays a distance of 0.00 miles,
you’ve reached your destination!
