Even though this has less to do with OSM on Garmin, I figured out it’d be nice to warn people (considering many are beginners here):
There are scam websites, positioned highly in Google, which pose as official Garmin map downloads, but their “support agents” will try to get remote access to your PC.
Jim Browning, a famous scam buster made a video about them.
