Depth, water temperature, and water speed metrics not appearing on the navigation chart of a GPSMAP 4xx or 5xx series chartplotter/sounder

The numbers will appear on the map page once the Data Bar has been turned on. These numbers are only available for a sounder model device (i.e. GPSMAP 547s) that have a transducer directly connected to the device. If a non-sounder model (i.e. GPSMAP 547) is being used, this information will need to be sent to the device over NMEA 0183 or NMEA 2000.
