All of the Jag Denso DVD Fibre Optic units will fit X Type and an S Type, the last two letters are the various revisions and updates, the further down the alphabet on the last letter the younger the unit from memory.
Thanks so much Barry W for your reply to my last inquiry. I did find a used DVD drive at very reasonable cost that solved the problem for now. Since I never use the SAT/NAV function, I was wondering if anyone has ever tried just pulling the disc out and driving like that since the DVD drive's failure to read the disc seems to cause problems? It would seem if the drive isn't spinning that one might encounter fewer problems in the long run. Thanks so much again for any response......
My understanding is that the drive powers all audio to the Head including CDC, CD and Voice if you have it...having said that, try it, you have nothing to lose.
Incidentally the DVD drive on the S Type is from 2002, previously I think they had an non Fibre Optic system.
