+       This module does not support direct transfer of .GPI files to
+       receivers in Garmin protocol mode.  For units like Nuvi, Zumo, or 
+       Streetpilot, just choose a file that's on the drive where your
+       GPS is mounted.   For units like the X series (GPSMap60, etc.) 
+       you must explictly put the unit in mass storage mode or mount
+       the memory chip in an external reader and transfer the file 
+       directly.
