Anyone fixes the drive error on a cdc40 Delphi Grundig? Mine is saying all 6 cds are in, though they was as it had 6 cds in it when I took it apart. Which are now removed but its stuck on cd no 6 slot. Was a £15 ebay bargain and in piano black too so if I do have to get another unit and swap the fronts its not the end of the world
