Map Fix

Map Fix is used with charts or maps. This system asks for a reference

position in latitude/longitude, which you take from a marked location

on the map. It then shows the present position as distance on the map

from that reference point.
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you

then measure up four inches and to the left a half-inch from the refer-

ence point on the map to find your location.
To configure a map fix:
To use this format, you need to follow these steps in order. First, take

your map of the area and determine a reference latitude/longitude.

(Note: in order for this system to work, the latitude/longitude lines

must be parallel with the edge of the map. USGS maps are parallel,

others may not be. Also, this works better with smaller scale maps,

such as 1:24000.) The reference position can be anywhere on the map,

but the closer it is to your location, the smaller the numbers will be

that you'll have to deal with.
Once you've decided on a reference position, you can save it as a waypoint.

See the waypoint section for information on saving a waypoint. Save the

reference position as a waypoint. Exit from the waypoint screens.
