I downloaded the new version of MapSource, and yes, now it seems to be able to download .loc files.
Is there a way for MapSource to display all waypoints together? Each .loc file I bring in to MapSource makes its own little file. Seems like it would be nice to be able to see them all together.
I tried GSAK, and told it to transfer all waypoints from my GPSr to it. It gave me an error message saying "error sending waypoints, MAGPROTO: no data received from GPS." My GPS is turned on and had been sending and receiving fine from other programs, so I'm not sure what's wrong.
