The writing is on the wall. There has been a widespread rumor that Garmin stopped developing Basecamp, and now they have officially stated it - see this: https://support.garmin.com/en-CA/?faq=cmo7YxRdRB1DDl1JAWuEV8 "BaseCamp development has been discontinued." It appears they will begin pushing people to a web portal to manage their GPS devices, as described in that article. Their new inReach units and the GPSMap 66 (their newest handheld) are the only current devices that can use the portal now. But with Basecamp discontinued, it seems like this is their new solution. This is bad news, because the current version of Basecamp/MapInstall cannot send maps to your GPS. When you try, everything seems to work OK, but when you look at the map on the GPS, it has no detail. So you can't send a third party map to your device now, like the maps at GPSFileDepot or my maps. My solution is to offer a separate download of the map file to install on the GPS, avoiding the use of Garmin's software. There are tons of threads about this problem on the GPSFileDepot forums from confused users who can't install maps. The only solution is to downgrade to an old version of Basecamp or use Mapsource. I always assumed this was just a bug that would quickly be fixed, but it's been 7 months now and since they've abandoned Basecamp, I guess they will never fix it. And there is a special concern for Mac users.... Basecamp is a 32-bit application, and the next version of MacOS (due in the fall of 2019) won't support 32-bit apps. Garmin promised to upgrade Basecamp to 64 bit in 2018, but it never happened. So I suppose this is another reason why they might push everyone to a web portal in the future.
