The only thing I've seen for Nadin is related to the Windows XP operating system. Apart from that, no other information is given. Also, the software belongs to the VolksWagen Group and in 99% of the cases, they don't offer software for public use. You'll have to get in touch with the local Volkswagen dealer for additional details.
