Hi,
Had cruise fitted at the VW dealer,mine is a 2012 model year,as far as I can gather it depends a lot on the M/Y as far as costs go,best I could get mine for was £290 all in,if it had been pre 2012 it would have been £165 inc.
I have a G revision stalk cruise kit that is Gen VW ,brand new and unused, spare from my edition 30 if needed, what else you would need I have no idea,Sorry.
