<H2>DESCRIPTION</H2>

<EM>v.out.gpsbabel</EM> allows the user to export waypoint, route, and track
data from a vector map into a locally connected GPS receiver or as a file in
many common GPS data formats. Translation is done via the 
<EM><A HREF="http://www.gpsbabel.org">GpsBabel</a></EM> program. 

<P>
Do not use as a primary means of navigation.


<H2>NOTES</H2>

<em>v.out.gpsbabel</em> automatically reprojects data from the 
projection settings of the current location to Lat/Lon WGS84.
<p>
GPX format is used for data interchange between GRASS and GpsBabel.
If the requested output is GPX, then <tt>gpsbabel</tt> is never run.
<P>
The <b>layer</b> option is only used in conjunction with the
<b>where</b> SQL query option.


<H2>EXAMPLES</H2>

<h3>GPX Export</h3>

Export a vector lines map to a GPX track file:
<div class="code"><pre>
v.out.gpsbabel -t input=trail output=trail.gpx
</pre></div>


<h3>GPS device connected via USB adapter</h3>

Export vector maps named <i>waypoints, tracks, routes</i> to a Garmin GPS
connected to /dev/ttyUSB0:
<div class="code"><pre>
v.out.gpsbabel -w input=waypoints format=garmin output=/dev/ttyUSB0
v.out.gpsbabel -t input=tracks format=garmin output=/dev/ttyUSB0
v.out.gpsbabel -r input=routes format=garmin output=/dev/ttyUSB0
</pre></div>
