I know some people were looking for a Renault cd changer cable.
Ive just had a new changer fitted and asked the bloke to remove the cable for me, he said that it would have taken him a whole day and have to take the car apart to get it out coz it was wound in with all the other wires an stuff.
Anyhow, he recons that most newish Clios will have this cable fitted at the factory "just in case" a cd changer is ordered and has found this before when a Renault dear told a customer of his that hed have to buy one, the car already had one.
