Good Evening everyone, first post here, but I've been a lurker for a little while now. I just recently purchased a new 798 HD unit. I've taking a few recordings and have uploaded the recordings to Humviewer, marked spots on there and exported them to HumPC. I then export the waypoints from PC directly to my SD card. I then put the card into my unit and for some reason my waypoints are not pulling up on the unit? The recordings are there, just not the waypoints I've created? I've checked the SD card in HumPC and it clearly shows the waypoints are on the card in .gpx format, however I've tried everything to get them to pull up when inserting the SD card into the unit. Anyone know of anything I'm missing? I'm pretty decent computer wise and thought I would be able to figure this out, however I'm out of options at this point. Thank you for your help.
