Can you add a cd changer to a 2005 Jaguar Stype

it was a common prob with those cd changers in the boot/trunk disconnect it and let the head unit connect to it if still no good and the wiring/connectors are good the cd unit is faulty

If you are getting power to the unit and you hear it clicking and making a sound when you hit the eject button, the this means that a CD is jammed in the track and while it was changing it got stuck and now causes you to see an ERROR message.
What you do is while hitting the eject button, wiggle the CD MAGAZINE up and down and side ways. This will cause the CD to fall into place and your magazine will pop out.

Yes. They can install a cd changer on your trunk. Have an audio shop do it for you and guide you on the use the cd changer.

You can use your ignition key to open the boot, it has a key hole on or under the boot chrome trim

most cd changer magazines are the same, the best way to find a replacement is the goto an audio/video retailer and speak with an agent about trying some in your cd changer.

i had to do the same thing for my 07 mercedes c230 due to the fact i wasnt paying $150 for a piece of plastic

check the fuse for the factory amplifier tho generally when that is blown you have no sound at all

TRY REMOVING THE RADIO FUSE & WAIT A WHILE. IT SHOULD RESET WHEN PLUGGING THE FUSE BACK IN.

had to replace player twice, luckily it was under warranty. FACTORY PLAYER JAMS EASILY !!! What I have learned is to put cd player in radio mode before ejecting instead skipping form disc to disc.

SOUNDS LIKE YOU HAVE A VERY EARLY MODEL CD CHANGER ALPINE UNIT THE S TYPE
USED A AUDIOVOX CD CHANGER HOPE THIS IS USEFUL
