Reference

‘Map Datum’ — 

Datums are used to describe geographic positions for survey-

ing, mapping, and navigation and are not actual maps built in the unit.  
Although there are over 100 datums available to choose from, you should 
only need to change the Map Datum if you using a chart or paper map that 
specifi es a different datum in the legend.  A list of Map Datums can be found 
in Appendix D.

WARNING: Selecting the wrong map datum can result in substantial 
position errors.  When in doubt, use the default WGS 84 datum for 
best overall performance.

‘North Reference’ — 

 Let’s you select the reference used in calculating heading 

information.  You can select from, ‘Auto’ ‘True’, ‘Magnetic’, ‘Grid’ or ‘User’. 
‘Auto’ provides magnetic north heading references which are automatically 
determined from your current location.  ‘True’ provides headings based upon a 
true north reference.  ‘Grid’ provides headings based on a grid north reference 
(used in conjunction with the grid location formats described on page 56).  
‘User’ allows you to specify the magnetic variation at your current location, and 
provides magnetic north heading references based on the value you entered.  

WARNING: If ‘User’ is selected, you must periodically update the 
magnetic variation at your present position.  Failure to update this 
setting may result in substantial differences between the information 
displayed on your unit and external references, such as a magnetic 
compass.

‘Magnetic Variation’ —

 displays the magnetic variation at your current loca-

tion.  If ‘User’ is selected for the ‘North Reference’, this fi eld is used to enter 
the magnetic variance.
