The Formats
Custom icons are supported on units that support that. Neither GPSBabel nor your firmware know what
is associated with any given slot number. They don't know that the picture you placed in the first slot is a
happy face, they only know they're in the lowest numbered slot. GPSBabel names the them consistently
with Mapsource, so they are named 'Custom 0' through 'Custom 511'.
For models where the connection on the GPS is a serial interface, be sure the GPS is set for "Garmin mode"
in setup and that nothing else (PDA hotsync programs, gpsd, getty, pppd, etc.) is using the serial port.
For models connected via USB, we recommend use of the usb: filename. For this to work on Windows,
you must install the Garmin driver. For Linux, this will fail if you have the garmin_gps kernel module
loaded. See the Operating System Notes [/osnotes.html] for details.
This module also supports realtime tracking which allows realtime position reports from a Garmin GPS
receiver over USB or serial.

snlen option
Length of generated shortnames.
This option overrides the internal logic to figure out how many characters an addressed Garmin GPS will
support when using the '-s' smartname option. This should be necessary only if you have a receiver type
that GPSBabel doesn't know about or if you want to "dumb down" one unit to match another, such as
wanting waypoint names in a StreetPilot 2720 (which supports 20 character names) to exactly match those
in a 60CS (which supports 10).
snwhite option
Allow whitespace synth. shortnames.
This options controls whether spaces are allowed in generated smart names when using the '-s' option.
deficon option
Default icon name.
This option specifies the icon or waypoint type to write for each waypoint on output.
