Thanks for all your help members, I obtained the correct cd changer for my standard head unit and used one of the links posted to buy it !
Just wondered if anyone has the standard head and A09 changer that has bought or knows exists a steering wheel remote for lazy people like me?

I believe the radio control buttons are on the actual steering wheel of the higher spec models?



Maybe Fiat can supply/fit one of these? (for probably a small fortune)
