Map Datum—describes geographic locations for 
surveying, mapping, and navigation and are not actual 
maps built in the unit. The default setting is WGS 84. 
The unit automatically chooses the best datum based 
on your chosen position format.
For more information about selecting Position 
Formats and Map Datums, see 
 in the 
Appendix.
  WARNING: Selecting the wrong map datum 
can result in substantial location errors. You 
should only change the position format if you are 
using a map or chart that specifies a different 
position format or map datum or want to use 
a format you are familiar with.When in doubt, 
use the default WGS 84 datum for best overall 
performance.
