OK never mind.
It didn't work the way you said, but I used my extensive IT training over many years to figure out to put an SD card in the COMPUTER slot, then Humminbirdpc saw that and let me upload from the F: drive (the SD card), but NOT the .gpx file.
Whatever, I now have the .hwr extension file for Greeson on an SD card and am about to go out into the dark night and plug in my HB DF and see if I can upload this file.
back in a few
Thank you guys.
