Garmin Express stalls at 18% when attempting to update to the latest maps on a 2597 LMT. There is no error message. The software on the PC and the device have been connected all night, twice, restarted in between, both, and the same thing happens every time. Both Garmin Express and BaseCamp claim all the software is up-to-date.
How can I update the maps when Garmin Express doesn't work?
