[Gpsbabel-misc] Magellan error

[Ryan <rt...@ch...>]

I have used gpsbabble and gsak before, but now I can't convert my SD 
card files to anything useful
I have tried a converting to a loc file but gsak won't load it, I get a 
0 waypoints loaded dialog, then I am stuck I also tried a gpx format 
same outcome, so I guess my question is this magellan sd card as in 
magellan, dosent appear to convert, what is the filename extension for 
magellan meridian files?
