	GPSBabel supports a wide variety of Garmin hardware via serial
	on most operating systems and USB on Windows, Linux, and OS X.
</para>

<para>
	For serial models, 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.

</para>

<para>
	None of the GPSBabel developers has access to every model on that
	list, but we've received reports of success and/or have reasonable
	expectations that the above models work. If you succeed with
	a model that is not on that list, please send a message to the
	gpsbabel-misc mailing list with the details so that we may add it.
</para>

<para>
	Not every feature on every model is supported.  For example,
	while we do extract data such as heart rate and temperature from
	tracks on the sporting models like Edge and Forerunner, GPSBabel
	is not a fitness program at its core and does not support features
	like workouts or calorie/fitness zone data. Furthermore, sporting
	models don't support track upload. When trying to upload tracks to
	these devices, GPSBabel converts them to courses on the fly and
	uploads these instead. When uploading waypoints at the same
	time, these are converted to course points by mapping them to the
	nearest track point on the track/course (no matter how far away from
	the track they are). Since course point creation requires time
	stamps for the track points, they are created automatically assuming
	a speed of 10 km/h for tracks that lack them.
</para>

<para>
	To communicate with a Garmin GPS serially, use the name of that
	serial port such as <filename>COM1</filename> or  <filename>/dev/cu.serial</filename>.
</para>
<para>
	To communicate via USB use <filename>usb:</filename> as the filename on all OSes.
	Thus, to read the waypoints from a Garmin USB receiver and write
	them to a GPX file:
</para>

      <para><userinput>gpsbabel -i garmin -f usb: -o gpx -F blah.gpx</userinput></para>

<para>
	If you have multiple units attached via USB, you may provide
	a unit number, with zero being the implied default.  So if you
	have three USB models on your system, they can be addressed as
	<filename>usb:0</filename>, <filename>usb:1</filename>, and <filename>usb:2</filename>.  To get a list of recognized devices,
	specify a negative number such as:
</para>
	<para><userinput>gpsbabel -i garmin -f usb:-1</userinput></para>

<para>
When reporting problems with the Garmin format, be sure to include
the full unit model, firmware version, and be prepared to offer
debugging dumps by adding <option>-D9</option> to the command line, like:
</para>

      <para><userinput> gpsbabel -D9 -i garmin -f usb: -o gpx -F blah.gpx</userinput></para>

<para>
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'.
</para>
<para>
	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.
</para>
<para>
	For models connected via USB, we recommend use of the <filename>usb:</filename>
	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 <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="/osnotes.html">Operating System Notes</link> for details.

This module also supports <link linkend="tracking">realtime tracking</link>
which allows realtime position reports from a Garmin GPS receiver over USB
