I've been looking for this image for five months, unfortunately nothing.
My HDD/DVD is fine, but it's stuck at 97% map update. Now on every car it starts asking for DVD 1 or 2 and ejects them (different media, write speed, no luck). The problem is that new maps require newer telematics software (different partitioning).
Without Xentry online there is no way to go back or format.
I would be satisfied with the old maps 12/13/14/15 (image). The last ones are from 2018, they are old anyway.
