displayed on the GPSMAP 176. When in doubt, seek assistance.
If you are using a map or chart in conjunction with your GPS,
make sure the settings under the ‘Units’ tab of the GPSMAP
176 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.
