I've got it. It's really working nice and adds a lot of features to EOS. Worth every penny. And I don't understand why VW didn't do it in factory by default.
Are you from Turkey ?
I've got one too and have been happy with it.
Some of its features already exist, but must be activated with VAGCOM or by a dealer - no doubt some are being saved by VW for future model upgrades.
Some - such as being able to open the roof on the move (an option I don't use), VW would not offer due to the warranty risks - that roof is an expensive piece of kit.
