Map update available on Garmin Express. I updated 6 units and had to keep clicking install now 2 or 3 times on each unit then it installed ok. Then when clicking install to computer and it started activating maps for a couple of seconds it would get an error message installing update. Kept clicking install to computer several times until finally the windows installer appeared. This happened on both my windows 11 laptop and windows 10 desktop. I am using latest version for express 7.28.0. Anyway all 6 are loaded with 2027.10.
