Ok. So I am a newbie and have been tinkering with Garmin Basecamp for a while now running on a Mac. So, here is where I also claim the prize. I have downloaded a couple of GPX files with a view to import them into Basecamp and TX them to my GPS unit. No matter what I do, I cannot get the files to import to Basecamp. I am absolutely sure that the fix is simple, just that I cannot see it.
