Yes. I've also patched out the CID check, and ran a few experiments:
1) Copy old map (~2015) to another SD card - works.
2) Copy new map (2020) to VW SD card - fails.
3) Copy new map (2020) to another SD card - fails.
I suppose the navigation software might be too old.
According to the internet, go to the folder \maps\00\sds and remove unwanted speech sound files (e.g. FR french, DE german, ES spanish, FI finnish, etc.) - that should free up enough space for the files to fit on your SD.
