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, oth-
ers may not be. This works better with smaller scale maps.

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. Now exit the waypoint screens.

From the Coordinate System menu press

the map's scale. This, typically, is at the bottom of the paper map. It's
