    Anyone got experience with Jaguar XJ audio (1998+)?

    Hi all

    I have a 2002 Jaguar XJR with the premium Alpine 9 stereo audio system with CD changer. The head unit/fascia can be seen here: http://i4.photobucket.com/albums/y12...t/PICT7142.jpg (that's not my car, but a similar model.) The lower unit controls CD, radio, tape, sat nav and the telephone.

    I'm looking to get this hooked up to a car PC, but I really know nothing about how it is wired and therefore what I can hook into with my PC. I've ordered a technical manual for the car, but I was wondering if anyone has any experience with the 1998-2002 Jaguar XJs and could shed any light on how it is setup.

    I'm not sure what extent I will be going to yet. I may keep it simple, and simply install some buttons to control a trunk-mounted PC, and thus keep the existing fascia untouched. Or I may go all out, remove the entire audio/sat-nav/telephone fascia and replace it with an LCD that controls a car PC. The whole-hog approach will be quite complex because I don't want to lose use of the telephone, so I somehow need to retain the controls for that.

    Any advice would be much appreciated!

    There is little chance of integrating you current AV/SAT NAV/Radio with the carputer, certainly not without major hacking, UNLESS there is something like the I-bus in you car. You need a Jag specific forum.

    Removing everything could also be problematic, and not just because you will lose the phone.

    Good luck

    Thanks for your reply.

    I don't want to use the existing sat nav/CD/FM. The CarPC would provide those functions itself, if I went that route.

    What I'm more likely to do is have a CarPC that just does MP3s - in that scenario I would want to be able to hook its audio up to the existing Jaguar audio, probably spliced in-line with the CD.

    So I was just wondering if anyone had done that already and knew how the Jag audio was wired.

    Then I would suggest the following

    Get an mp3 player
    Go to a jag forum, and find oiut how they integrate mp3 players (like an Ipod) and do that.

    It makes no sense to create a carputer that will take significantly more time and money then an Ipod and AUX-In for your car, or tape adaptor, or wireless RF adaptor.

    Goodluck

    if you ONLY want mp3 capability, go Wiredwrxs route.

    Spending the time and the money to put a PC in your car JUST to play MP3s is an extremely expensive and tedious way to accomplish that.

    I wasn't sure if you had the base radio or the "Premium" audio system.

    2002JaguarXJR-RadioWiringDiagram - PremiumSystem.pdf

    If you were thinking about hi-jacking the CD-Changer Audio lines for your computer/mp3 player, that would certainly be possible with an audio switch box of some kind.

    Sorry, but I can't help you with the which pins or wire colors - the diagrams are not very detailed. If you want to do that you will have to do some poking around yourself with a meter or perhaps a small speaker, but be careful.

    I hope this helps

    Thanks so much walky, that's an excellent start. Can I ask where you go that? Do you have any similar docs?

    To everyone else - yeah I agree a carputer is overkill for just audio. I may still go the ipod route. But I like the idea of a carputer because:
    1. I'm a geek and I like the idea of having a PC in my car
    2. I'm an audiophile - all my music at home is stored in a compressed lossless format, full CD quality. I'd like to have this in the car too
    3. Similarly, I'd like to have better quality output than an ipod would provide - e.g. using an M Audio soundcard on the PC
    4. I may want to add other functionality later, particularly sat nav. The one built into my car is from 2002 and is somewhat dated - e.g. it can't search for an address by postcode, so it's really slow to use.

    Still don't know what I'll do, just checking out my options.

    Thanks again for your responses.

    I get the diagrams through my local public library's website. The service is called "Power Library", your state may have it. Anyway, I have access to wiring diagrams for most cars. If you need something specific, I can try to get it for you.

    Peace.
