I am fairly new to QGIS and GIS in general so it's hard to tell what I'm doing wrong.
I am using a GPSMap 64st and can't seem to successfully upload any GPX files to it through QGIS.
I am able to select the correct data layers in the GPS Tool, can select my GPS device, and am using the USB port. Everything looks good and then I press 'OK' and the window closes but nothing happens. No error message, but when I check my GPS nothing is on it.
I have tried 'Edit Device' and adding in a new device as described here:
Quantum GIS – using a USB GPS device.
But it hasn't worked either. Also somewhere else I saw to change the commands provided in the link to use gpsbabel instead of %babel and that hasn't worked for me either. I also have separately downloaded the babel software just in case although I thought you should have that automatically installed with QGIS?
I'm using QGIS 3.4.14 although I tried in 3.10 too with no luck.
I am able to successfully download data from my GPS, although I usually just use the 'Load GPX File' in GPS tools and select the files directly from my Garmin in the file explorer window, I'm not sure if this is normally how you're supposed to do this.
I also have successfully uploaded the very same GPX files to my GPS using other programs (Ozi and DNRGPS) but I would like to be able to do this using QGIS.

When exporting to gpx, choose Format = GPX, CRS = EPSG:4326 - WGS 84, don't use UTM, FORCE_GPX_TRACK = YES, these are essential. The CRS must be WGS84 and the EPSG for your area.
