Ok, I just saw the same problems on a friends computer. Took his GPSmap64 to my computer and everything works fine. Since he was unable to fullfill the first steps it might be a difference within the tools used.
I'm using imgTool 1.9.4 and gimgunlock.exe with a file date. I was unable to see what file version it is. It could also be a problem with the virus protection or the operating system. Try to disable the virus protection before changing the img-file.
And I have Win7 as OS, maybe a newer OS could be the problem? No further idea right now, sorry. Offline Joined: Wed Dec 02, 2015 4:43 pm Posts: 2 Has thanked: 0 time Been thanked: 0 time.

And if it is how? - With a empty sdcard make a folder 'GARMIN' and placed inside the unlocked image file for Europe.
- Boot your satnav and see if it reads. If its still locked your unit may have the latest protection so follow post #29 by @OldMan0815 and run the img through gimgtools 0.03 and then set the codepade to 1252 using ImgTool 1.9x offline Joined: Wed Jun 05, 2013 11:03 am Posts: 4 Has thanked: 0 time Been thanked: times.
