Load the gpx file into humminbird pc, then send to SD card. I'll look to see the exact language it uses.
Once you see your .gpx file in humminbird pc, right click it and select upload (to your sd destination).
Select replace.
If you get a waypoint name error, stop, figure out what is wrong and correct it or it may corrupt your memory in your depth finder. (don't ask how I know this)
This will create a file on your sd card with a .hwr extension. It may be under a misc folder.
You can then plug the card into your unit and it will upload.
