First of all hi to all. Well here goes,My dad has a vectra with a ccr600 which works fine,he asked me to get him a Cd Changer (CDC2).I have managed to get 1 from a salvage yard and fitted it. The problem is now the display shows "CD Safe" & also the changer did not come with a code. I have read all the posts but could not find any on how to remove "CD-Safe" from the changer. The numbers on the side are as follows GMCDC2w0748626 & 7607775322 also there is this number 90569379.Can anyone help me. many thanks.
