Updating maps - Kamiq (January 2021) - Amundsen

Hi All,
I'm used to updating the maps on my Columbus MIB3 unit via SD Card, I'm not too sure of the process on my wife's new Kamiq.
First question - I assume that the unit will be a Amundsen MIB3 unit?

I've fed the VIN into the update portal and downloaded the latest maps. I exploded the, like, 708 folders into the root of a USB drive formatted in ExFAT. Inserted into one of the front USB ports and....nothing.

At the moment, the system information is as follows:

Device Part Number: 3V0035816D
Hardware: H22

Software: 0306

Navigation Database: 20.3

Is this by chance already on the latest version of the maps?

If not - is it just a matter of plugging the USB stick in and waiting as it all updates silently? On my Columbus unit you get a nice screen indicating the process, the percentage you're through it etc.

Cheers
