and Speed, Temperature, and Direction Display.

temperature sensor in the water.

Letters. This setting is used in all fields that relate to direction

Location Tab
NOTE: The Location tab settings affect how navigation
information is displayed on the GPSMAP 176/176C. When
in doubt, seek assistance. If you are using a map or chart in
conjunction with your GPS, make sure the settings under the
Location tab of the GPSMAP 176/176C match that of the map or
chart. This information should be displayed somewhere on the
map or chart. If the information is not present, contact the map or
chart maker to determine what position format, datum, heading,
and units of measure are being used for the map or chart.
