<para>Read-only support for the csv file format used by <productname>Visiontac VGPS-900</productname> and <productname>Columbus V-900</productname> GPS data loggers. These seem to be two brand names for the exact same product.</para>

<para>The the V-900 stores logs on a microSD card in a custom csv format. This format contains NULL chracters and fixed length fields, and therefore can not  be handled by the normal csv module in GPSBabel.</para>

<para>
The device support logging of trackpoints, waypoints, and voice recordings (.wav files).
</para>

<para>If you create voice recording waypoints, a link (url) to the corresponding wav file is added to the waypoint.
If you happen to use this for OpenStreetMap.org project, you can easily click on a waypoint and open the wav file from within JOSM. For this you must use gpx version 1.1 as the output file. The next example shows exactly how to do that.
