I have Mazda NB1 and, having failed to be able to update it on my MAC, borrowed a Windows 10 laptop to use that to update. Tom Tom Home latest version installed, connected to the SD Card from the car but, having selected to update maps, the warning not to remove card and ensure laptop is connected appears, but clicking "OK" does nothing - the same screen stayed for 5 hours but nothing seems to have happened. Uninstalled and reinstalled TT Home, but still the same problem - screen shot attached.


Clicking "abort" and any of the other TT menu items also do nothing.

Killed TT Home application by the Windows Taskmanager. Removed files from SD-Card manually, then the update went fine.
Let us know the results of your struggle 😁.
The issue here seems to be related to what I explained in my comment here-
