This format can...
read and write waypoints
read and write tracks
read and write routes
This format has the following options: date, datum, dist, grid, prec, temp, time, utc .
This is a textual format that contains nearly all of the information contained in the MapSource™ main format, GDB. This format also contains some computed values such as distances between routepoints and trackpoints, speed, and course (heading).
The main goal of garmin_txt is to make aviation data more available. Because MapSource™ supports only the export, GPSBabel gives you the possibility to bring aviation data into MapSource™.
During the export with MapSource™, some fields are written using local settings of MapSource™ and Windows. These include grid format, gps datum, distance and temperature units, and the representation of date and time fields. GPSBabel tries to read all items automatically. Problems with date and time format can be solved with the 'date' and 'time' options.
Example 3.7. Command showing garmin_txt output with all options
gpsbabel -i garmin_txt,date="MM/DD/YYYY",time="hh:mm:ss xx" -f in.txt -o garmin_txt,date="DD.MM.YYYY",datum="WGS 72",dist=m,prec=6,temp=c,time="HH:mm:ss",utc=+2 -F out.txt
Read/Write date format (i.e. yyyy/mm/dd).
This option specifies the input and output format for the date. The format is written similarly to those in Windows. An example format is "YYYY/MM/DD".
GPS datum (def. WGS 84).
This option specifies the datum to be used on output. Valid values for this option are listed in Appendix A, Supported Datums.
Distance unit [m=metric, s=statute].
This option specifies the unit to be used when outputting distance values. Valid values are M for metric (m/km/kph) or S for statute (ft/mi/mph).
Write position using this grid..
This value specifies the grid to be used on write.

Idx or short are valid params for this option.
Precision of coordinates.
This option specifies the precision to be used when writing coordinate values. Precision is the number of digits after the decimal point. The default precision is 3.
Temperature unit [c=Celsius, f=Fahrenheit].
This option specifies the unit to be used when writing temperature values. Valid values are C for Celsius or F for Fahrenheit.
Read/Write time format (i.e. HH:mm:ss xx).
This option specifies the input and output format for the time. The format is written similarly to those in Windows. An example format is "hh:mm:ss xx".
