For VolksWagen you find the map updates
On the moment there are still the updates from 21/06/2021 (V14).
I managed to find the links for the Discover Media updates from this month (V15).

Bundel 1 does not fit on a 16Gb SD-card, you must have a 32 Gb SD-card for that
The rest can be copied to a 16 GB SD-card.
By the way, I think the new maps (V15) will be supported on the official site (see first line) within a month.
Have fun
