1) Am I right in thinking that if opting for leather, heated seats are standard? Adding the 'winter' pack with leather would just add heated washer jets?
Pretty much yes.
2) How will the ride be affected by the 19" Wheels? I'm going for ACC for 'comfort' on longer trips and due to very poor road conditions in my area. Will it be noticeable both in terms of road noise and general comfort? I personally prefer the Santiago wheels over the Austins hence going for them but concerned about there overall effect on the vehicle.
Not sure about this, but I test drove a Rocco with 19's and it didn't feel any worse than my own Rocco with 18's
3) Is the Colour Display worth bothering with? I did read somewhere that it was now standard so not sure why it's shown as an option.
Standard - so don't worry about this
4) Does the DNS Pro have a database of fixed speed camera locations and altering around them? If yes, then does the 'standard' / 'basic' NAV have that feature also or is it only available with the Pro Nav?
None of the Nav units have speed cams, although they can be added pretty easily via SD Card as personal POI's. VW Germany have an area on their website dedicated to personal POI's with on line software that creates the files for you. Not sure if it just works with the more expensive Pro version tough ?
5) If going for the 'climate screen' - am I right in thinking that due to it's nature it blocks phone signal? Hence why you have to also combine it with the 'Phone Box' option? I really want the heated screen, but if it's going to cripple my iPhone which isn't supported with the 'Phone Box' then it seems fairly pointless.
Well, VW UK tell us that, but funny that other markets, you don't always have to specify advanced phone option with this. As the advanced phone package uses the RSAP protocol, you won't actually gain anything from it if you use an iPhone, as IOS devices don't support RSAP.
Does anyone happen to have a picture of a MK7 GTI with Leather? And/or a Night Blue on the 19" Santagios? Struggling to find a picture of either online. Just wanted to get a feel as to what it'll look like up and above what the VW configurator shows.
Sorry, can't help with that I'm afraid.
