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.
(Please note that in order for this system to work, the lati-
tude/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.) 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.
