I have a 2007 Sovereign with a CD changer and the sat nav touchscreen display. The CD changer is powered but when I press the CDC button nothing happens. When I go into the menu using '917' I can see that the CDC function is not enabled. Pressing the button appears to enable it but it doesn't work and when I key off and on again it is disabled again.
I have seen a few threads that state that you don't need to go to the dealer if you have a touchscreen but I haven't found one that specifically describes the steps that I need to take, the CDC was in the vehicle when I bought it; I believe, from the paperwork, that its been there from new.

 

CDC, is not the CD in the dash interior, it's mounted multiple disk unit) in the boot (trunk) on the LHD side behind the pull down panel where the Sat-Nav unit containing the disk is also. If the disk cartridge is missing, no function.

 

I don't have a problem with the CD player in the dash. The CD changer in the boot is loaded up.
