GPX files and BaseCamp in GPS technology and devices Posted January 13, 2012 · Edited January 13, 2012 by Grasscatcher What is the "Garmin E"? My interpretation of what "Garmin H" is is that it is your GPS.... and it is showing contents of the internal memory...only. And, as such, it doesn't appear to me that it is seeing the SD card. My file tree shows "Garmin GPS Map78S (G)", then immediately below it, as another drive, "SD Card (H)" What's confusing to me is that daily track files and daily waypoint files are in that location (H if that is supposed to be your card). Did you manually place those there?
