In Basecamp I mainly use Great Britain OS 1:25k Birdseye maps, which are in the Library along with my tracks etc. of hikes. In the Maps menu I have the Global Base Map (which gets installed with Basecamp) selected. However the Global Base Map road labels (but not the actual roads) and areas of sea labels show over the top of the Birdseye maps. Changing the dropdown Detail Level menu has no effect. This sometimes obscures detail on the Birdseye map.
I'm sure on a previous installation of Basecamp on an older PC I had installed a different Global Map which was an empty map (no detail of roads, land, sea) as recommended by someone on this forum. That was 3 or 4 years ago and now I can't remember where I got the map from. I may even have overcome the issue on my current PC until I installed the latest version of Basecamp as I don't recall having this issue again until the last couple of months.
Any suggestions?
