Hy there,i have a fiat stilo wits a simple a/c controler and i want to know if i`ll buy this http://www.ebay.co.uk/itm/Fiat-Stil...arts_Vehicles_CarParts_SM&hash=item3f0fb24388 cotroler can it work? or does it need something else?

The manual and digital climate control systems are completely different.

To fit digital climate control, you would also need to replace the complete heater/air conditioning box and wiring. There's a guide here: https://www.fiatforum.com/stilo-guides/314709-how-abarth-interior-your-stilo.html

Thanks a lot
