Garmin GPS 40 - Manual (Page 39)

The GPS 40 features a powerful moving map
display that can do much more than just plot your
course and route. The Map Page also provides you
with a moving map cursor that will let you pan
ahead to nearby waypoints, determine the distance
and bearing to any map position and mark new
waypoints while you navigate.
The Map Page can be broken down into three
main sections:
The zoom function and panning control fields
are located at the top of the screen. There are 12
selectable zoom ranges from 0.2 to 320 miles or
0.5 to 600 km, measured vertically.
The map portion of the page is bordered by an
8 x 10 grid to help you estimate distances based
on the map scale you are using. Your present posi-
tion is indicated by a position diamond, with your
track and/or route displayed as a solid line. Nearby
waypoints are represented as squares, with the
waypoint name also listed. You may select which
of these features are shown through the map setup
submenu page (see page 43 for more information).
The last fields directly below the map show your
bearing and distance to one of three selectable des-
tinations: an active destination waypoint; a high-
lighted on-screen waypoint; or to the panning tar-
get crosshair. Your current track and speed are dis-
played just below the bearing and distance fields.

The GPS 40 has on-
screen range rings to
help you estimate dis-
tances relative to your
present position. The
value of each ring is
determined by the cur-
rent zoom scale.
The distance value of
each ring is equal to
1/5th of the current
zoom range, with the
interval of each ring
noted below the first
range ring.
To turn the range ring
display on or off (the
default setting is off),
see the map setup
instructions on
page 43.
