To configure a map fix:
To use this format, you need to follow these steps in order. Take a 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. 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 you will be working with.
Once you have decided on a reference position, you can save it as a way-
point. See the waypoint section for information on saving a waypoint.
Save the reference position as a waypoint. Exit the waypoint screens.
