In my search for a good XK, I stumbled on a nice 8.
However, when I asked the salesman over the phone if he could look in the boot for me to see if the car has a cd-changer, he couldn't find it. Said there were some plugs dangling around though.

Now, assuming the worst case scenario; the car never came with a premium sound system.. Would it be possible to just find a cd-changer and retrofit it? Or would the non-premium system not even accept the addition?

What are my options? Obviously, just a tapedeck is unacceptable.

 

CD changers were optionally fitted to the standard sound system too, not just premium systems.
I am not sure however if the metal changer/amp housing will be in place if the CD changer was not specified at assembly. All wiring shoud be in place to retrofit though.

 

Just a guess, but if it's a convertible the metal housing is probably there. The convertible pump and reservoir sit on top of that metal housing.

 

So it should just plug in even if it never had one?

 

Yes, but it has to be a jaguar branded changer, the standard Alpine version is not compatible.

 

You can pick up a changer on Ebay at a reasonable cost.
