I called the previous owner; indeed he used a 'lifetime FSC' for the maps. So thank you for this info, it helped me to detect the source of the problem
Now the fix (also thanks for that), but how do you repatch the HU? I can buy an navigation update online (ConnectDrive store), create the USB drive, but (since the navigation is not loading) the HU will not detect the map-update (on the USB stick). How to get the original map-update (with an official FSC) on to the HU?
Hope there is another way to do it!
