I have a 2003 s-type jaguar with the premium sound. I am not getting any sound from the stereo. The navigation unit is working (but no sound) but the cd changer powers up but does not seem to read the cd's. I have checked the fuses and am getting power to the amp. Anyone have any ideas. Thanks in advance.

 

I had the same problem. If your battery is more than 4-5 years old, you may want to go ahead and change it. I had all sorts of electrical "gremlins" show up just as my battery was beginning to fail.
