Hi Folks I've got a 'W' reg Vectra CDX with CCR600 radio and a Blaupunkt 6 cd changer. I had work done on the car and they disconnected the battery so when I got it back there was no radio etc. I've put the code in for the radio and that works fine but when I try to play a CD I get a 'CD - SAFE' message. How do I enter the code? Also how do I remove the unit from the glove box so that I can take it to my local car audio place to get the code?
