Thanks for the reply. Yes, I did read the instructions on the main page, but when I ran the installer it appeared to me that it didn't install the map. I uninstalled it, then re-downloaded it and once again ran the installer. When I open BaseCamp, it does show "My Trails" as a map. However, it's nothing like what I expected, and nothing like the example pictures shown on the main page. The first screenshot below shows the area (Lassen National Park) using the Basecamp global map. The second shows the same area using the "My Trails" map. It doesn't seem to be a map at all, only a few trails (no contours or background). What am I missing?
