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 way-
point. See the waypoint section for information on saving a waypoint. 
Save the reference position as a waypoint. Exit from the waypoint 
screens.
