Long time Garmin user (>10 years), never had an issue until now. I've had this 2557LMT for about a year, and updated the maps at least twice with no issues. Then I 'updated' the OS to Win 10. Express still launches when I connect the GPS; but now it wants me to pay to update the maps. NOT GOING TO HAPPEN!
Support responded to my e-mail with the usual, check your cables (same as before, and the still work with everything else), check your connection (not an issue), check to see if Express needs updates (it doesn't).
This sure smells like a compatibility issue between Garmin Express and Win 10.
Anyone?
