Hi, my turstworthy 3790 is in need of a map update. Have done this several time before with Garmin Express. But today, I get a Memory full, error when trying to download (Windows 10), to the device. Tried putting in a brand new 32 GB micro card (Sandisk), which shows up just fine in Explorer/File viewer - but no luck.. Says device is 97% full - any ideas ?
