Garmin GPS 90 - Manual (Page 45)

The GPS 90 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 and review nearby
waypoints, determine the distance and bearing to any
map position and mark new waypoints.
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 port i o n of the page is bord e red by an
8 x 10 grid to help you estimate distances based on the
map scale you are using. Your present position is indicat-
ed by a plane icon (in track up mode), or a position dia-
mond (in other modes), with your track and/or route dis-
played 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 51 for more information).
The speed, distance and angle fields, located direct-
ly below the map show your bearing and distance to one
of three selectable destinations: an active destination
waypoint; a highlighted on-screen waypoint; or to the
panning target cro s s h a i r. Your current track and speed
are displayed just below the bearing and distance fields.

Overview
The GPS 90 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 curr ent 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 51.
