Hi all, I have the OEM CD changer in the cubby hole of my Z4 and when I bought the car all was working well. Unfortunately a few days ago while it was changing disc it suddenly reported No Discs and switched to the radio. I ejected the cartridge and reinserted it and it seemed to sort itself, however it's just happened again and this time reinserting the cartridge has not fixed the issue. Has anyone experienced this or know of any solutions?
