Just bought the wife a 1998 Megane Scenic. It only comes with a std radio cassette, everything she owns is on CD. I'm trying to keep the car as std as possible so want to fit the std Phillips 6 disc changer in it. I can pick these up pretty cheaply via ebay but am not sure where they would normally be installed in a factory fit option and whether the loom is pre-cabled with the changer control cable. Any pointers??
