a different position format or wish to use a format you are familiar with. The default format is 
latitude and longitude in degrees, minutes, and thousandths of a minute (hddd°mm.mmm’). The 
following additional formats are available:

•   Map Datum— allows you to manually select the datum reference used to determine a given position. 

The default setting is ‘WGS 84’. The unit will automatically choose the best datum depending 
upon your chosen position format. Datums are used to describe geographic positions for surveying, 
mapping, and navigation and are not actual maps built in the unit. Although over 100 datums are 
available (as listed on pages 65-66), you should only change the datum if you are using a map or 
chart that specifi es a different datum.
