Just checked with VWCS and have been told that the Generation 2 DNS and DNS Pro Systems are only available for the Passat and might be available further on in 2015 for the Golf.
Got the info on the Generation 2 DNS and DNS Pro systems and they are much improved especially the DNS which comes with a 6.5" Screen, 4 times better graphics, 150% faster processing and many new features including Car-Net Mirror Link etc
Pity these two systems won't be available for the Golf in the near future.
