radio works but multi changer not working says no cd when selected what do i do

Hi, this is usually down to a bad CD changer - however the telematics systems run on a fibre optic ring and a fault elsewhere could also be causing the problem. In the first instance I would have the car checked on a diagnostic tool to see if any fault codes are stored & to check all components on the fibre optic circuit are communicating. As said it is usually as simple as a bad CD Changer - you could try unplugging the wires from the changer & reconnecting - sometimes this may reboot it back into life but otherwise it may need repair or replacement of the changer itself. Some car audio specialists may be able to repair depending on what has gone wrong, otherwise from a dealer it will just be a new unit. Best regards, Paul
