Not sure exactly but I didn't spend more than £700 . I installed mostly by myself and coding was done by someone . ( but I know how to code now )
Got the cic+ screen+combox on eBay USA . Some guy from panama was selling . I paid $500 and about £90 to customs when it got to uk .
I bought the cic controller from Germany €40 . Climate control was about £60 on eBay . DIY for the climate control was on this forum I think .was quite simple .but independent ventilation don't work .
