Selecting A Different Heading Reference - Garmin GPSMAP 276C Owner's Manual

The default setting is WGS 84. The unit automatically selects the
best datum depending on your chosen location format.
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.

Selecting a Different Heading Reference

You can select from Auto Mag Var, True, Grid, and User Mag Var.
Auto Mag Var provides magnetic north heading references that are
automatically determined from your current location. True provides
headings based on a true north reference. Grid provides headings
based on a grid north reference (and is used in conjunction with
the grid position formats). User Mag Var allows you to specify the
magnetic variation at your current location and provides magnetic
north heading references based on the variation you enter. Enter
the magnetic variation of your current location in the Magnetic
Variation field if you selected User Mag Var for the heading.
WARNING: If User Mag Var is selected, the unit does not
automatically calculate and update the magnetic variation at
your present location. You must update the magnetic variation as
your location changes. Failure to update this setting can result
in substantial differences between the information shown on your
unit and external references, such as a magnetic compass.
