Hi All My Megane is fitted with a CD/Radio head unit that says Tuner list on the front. I have bought a new head unit and separate cd changer off ebay. However, i wrongly assumed that the head units would simply swap over with the same wiring locations as the new head unit has Update list on the front. Is there an adapter i can buy to make this fit or have i jumped in and bought something i cant use? Any help gratefully received - Thanks
