You can buy facelift headunits for reasonable money on eBay,but you have to make sure the ‘component protection’ has been removed,to allow them to be coded to your car.
I was going to upgrade to a ‘Pro nav’ unit and contacted ‘VW Retrofits’ in Reditch-they were very helpful.
Didn’t bother in the end as i wasn’t comfortable about putting 2nd hand parts in such a new car.
It was going to be £1200 for both parts including fitting-sounds a lot until you price up new parts from VW.
