           Default: /dev/gps

DESCRIPTION

       v.in.garmin allows the user to import waypoint, route, and track data from a locally connected Garmin GPS
       receiver via the gpstrans program by Carsten Tschach or the gardump program by Marc Hyman.

NOTES

       If  the  GPS  is  set up to output WGS84 Lat/Lon, v.in.garmin will attempt to automatically transform the
       coordinates to the current projection.  In all other cases, no checks are performed for datum, projection
       and format of data.  You must check for yourself that your receiver, gpstrans and GRASS use the same  map
       datum and projection.  The automatic transform may be skipped by using the -k flag.

       Route and Track data may be uploaded as points by using the -p flag, otherwise they will be imported as a
       line.  You  can  run  v.in.garmin  multiple  times  and merge the line and point vectors with the v.patch
       command if you want, but take care when merging dissimilar attribute tables.

       Future versions of GRASS will use gardump as the default download program. It can talk  to  newer  Garmin
       GPSs,  while gpstrans seems to be mostly abandoned these days and only works with older GPSs. The current
       version of gardump (ver 2.5) will not yet talk to USB-only GPSs, but you can try the v.in.gpsbabel module
       for those. The gardump code has been tested with an older Garmin GPS 45 and a newer GPS V and is expected
       to work with everything in between.

       Before running v.in.garmin, gpstrans should be set up to output WGS84 latitude-longitude, as follows:
       $ gpstrans -s
       datum:  100 (WGS84)
       format: 2 - lat/lon  ddd.ddddd
