Hands on with the Garmin GPSMAP 541s

The Garmin GPSMAP 541s Chartplotter is an incremental upgrade to the discontinued GPSMAP 540s.  The GPSMAP 541s has a 5″ diagonal color screen and the same Garmin appearance is maintained with the silver bars at the top and bottom of the case.  The major upgrade is the ability to interface with NMEA 2000 networks for engine diagnostics, weather instruments and additional uses.  The GPSMAP 541s comes pre-loaded with United States Coastal Charts and also has a SD card slot for additional charts.  The SD card can also be used for transferring waypoints, routes and tracks.  The GPSMAP 541s includes a built in sounder module, that allows direct connection to a transducer for depth and fish finder functions. read more
