My son has just bought an S reg Vectra with a factory fitted Philips CAR 400 radio. He was offered a Blaupunkt CD changer which he was told came out of the same car with the same radio fitted. We managed to find the CD connector tucked behind the glove box and plugged it in. Nothing happened and then we figured that a fuse needed to be fitted for the changer. Fitted fuse but the radio refuses to acknowledge the changer is there? He's been told he needs to put in a code (which he's got) to 'activate' the changer? The changer model/type is CDC2 (940 462 566). Anyone know if this combo will actually work and if so, how do we get it to recognise the changer? I've checked the back of the radio and there is a CD connector which is wired to the plug we found so obviously it can have a changer connected to it. TIA cheers, Len
