Re: File Format for Furuno
I have a 1720c and it uses a proprietory Furuno format outputing files named GP1650B.ROU, GP1650B.RAT, GP1650B.MRK, GP1650B.TRK. The 'rou' file contains waypoints, 'mrk' marks and 'trk' track plots. I use a utility called the GPS Utility read and edit these files. It has fantastic support from the designer so I can highly recommend it.
