On some models it may not be pre wired for the cd changer as some models come pre wired in some cases and in other cases they may not be pre wired.In this case you would want to speak with a dealer with your vehicles VIN number to see if they can tell you if it is pre wired or if they can get you the correct wiring and components you need to make this work.
After it is installed a dealer may have to program some of the computers/control units for it to operate properly.
