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
To configure a map fix:
To use setup a map fix, follow these steps in order. Take your map of the area and determine a reference latitude/longitude. (Please note that 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.) The ref- erence position can be anywhere on the map, but the closer it is to your location, the smaller the numbers will be that you will have to deal with. Once you have decided on a reference position, you can save it as a waypoint. See the waypoint section for information on saving a way- point. Save the reference position as a waypoint. Exit from the way- point screens.
