Hi, had same problem with ECE 2022 unzipping HIGH12_P195_EU_202145.zip. On Mac it doesn’t worked, then tried Unarchiver, it was unzipped, in car it showed update data available after plugging card in slot, but when I pressed update software, nothing happened. Then I download it again on windows, tried winzip - error with unzipping. So then I tried default unarchiver from windows and directly copied it to SD Card and now when I press update software it shows NavDB 2022 continue so I am going to do it today 🙂
BTW question to all who use Columbus. When I am in information about version, press update online it shows me License is not available, but that’s not true because I have all paid, locking unlocking everything works except this update online function. Also maps update online doesn’t show new updates, I must do it by USB.
