Garmin 66i, USB, and Linux - dealing with FIT files

• Using a USB cable to copy files from the 66i

I just finished going through the ordeal of copying the track from a recent hike onto my linux desktop. When I did the copy, I renamed it to "carrie.fit". The name "carrie" relates to place we hiked to.

So what the heck is a "fit" file?

file carrie.fit
carrie.fit: FIT Map data, unit id 84050944, serial 1409286145, Fri Dec 20 09:32:38 2024, manufacturer 4741, product -193, type -1

Converting it using gpsbabel

GPSBabel Version 1.8.0.  https://www.gpsbabel.org

Usage:
    gpsbabel [options] -i INTYPE -f INFILE [filter] -o OUTTYPE -F OUTFILE
    gpsbabel [options] -i INTYPE -o OUTTYPE INFILE [filter] OUTFILE

    Converts GPS route and waypoint data from one format type to another.
    The input type and filename are specified with the -i INTYPE
    and -f INFILE options. The output type and filename are specified
    with the -o OUTTYPE and -F OUTFILE options.
    If '-' is used for INFILE or OUTFILE, stdin or stdout will be used.

    In the second form of the command, INFILE and OUTFILE are the
    first and second positional (non-option) arguments.

    INTYPE and OUTTYPE must be one of the supported file types and
    may include options valid for that file type.  For example:
      'gpx', 'gpx,snlen=10' and 'ozi,snlen=10,snwhite=1'
    (without the quotes) are all valid file type specifications.

gpsbabel -i garmin_fit -f carrie.fit -o csv -F carrie.csv
gpsbabel -i garmin_fit -f carrie.fit -o gpx -F carrie.gpx
