CD Changer
I have a 6 CD changer in the boot of my '95 XJ6 Vanden Plas, which looks fairly new, but tends to work sporadically. The magazine with the CDs in it seems to sit loosely; actually the whole inside workings seem loose, but I would imagine it has to have a "floating" capability for bumpy conditions. That being said, it has an odd code that isn't exactly an E code. The display either says "NO DISC" which isn't accurate as there are 6 of them in there (correctly inserted, BTW 
) or it says: " ---------H "
Any ideas? Local auto audio shop says probably needs a new magazine, but I can't figure out exactly what I have or where to acquire the correct replacement.
Any help would be much appreciated.

These changers can give problems, but usually in the form of not being "recognised" by the head unit itself. In this case, it would display the message "Not Cont". This is caused by a common, bad/non existent, solder on a joint inside the CD changer itself and has been covered extensively on here. A search of the archives using "CD changer fix/solder" or similar will show the problem, including pics.
This may or may not be your problem, but worth a look in any event.

In addition to the solder issue sogood mentioned, I recall another thread in which an owner found that he needed to add a shim of some kind, I think to keep the magazine pressed toward the disc transport mechanism. I can't remember what he used, but it was something he slid into the CD changer at one side of the magazine, maybe a piece of folded cardboard or a Popsicle stick. I just searched Jaguar Forums for "CD Changer Magazine" and didn't find it, but the subject heading may have been different. You might also try Jag-Lovers.com, XJ40.com and jaguarforum.co.uk since I may have seen this thread at one of those forums.
On our '93, disconnecting the CD changer and then reconnecting it has often cleared E codes and NO DISC errors, but we've never had the --------H error.
You're correct that the entire internal subassembly inside the CD changer case is mounted with soft rubber mounts to isolate the CD transport from vibrations.
Cheers,
Don

Isn't the Jag CD changer just a rebadged Alpine AiNet unit?
As soon as I posted this, I found the following
https://www.jaguarforums.com/forum/x...04/#post756054
As I recall the Jag unit is an Alpine CHM S-620 and all magazines for the "CHM" series (or maybe it was all "620" series?) are the same
Cheers

If so, I wonder if a particular Alpine changer might be a plug/play replacement... guts or just as a complete bolt-in unit?
Also useful to that point:
https://www.jaguarforums.com/forum/x...-changer-4470/
Also, I generally had good luck with the Alpine changers, but I almost always had them mounted vertically. I wonder if that matters. Of course it could just be age too. Being shaken around for 15-20 years can cause some wear/tear on electronics that "jiggle"

I used the same magazine in my XJ40, X300, X308 and XK8's so it can't be that special.

Here's another interesting thread that you should look at with a potential free fix. Half way down the first page there is a PDF file that is very useful information.

I think you're both correct about the CD changers all being essentially the same Alpine unit. The only differences I ever heard of had to do with the electrical connectors and perhaps the head unit communications protocols (either the earlier or later ones were Alpine M-Bus - can't remember which). The magazines were the same for many years.
Cheers,
Don

Some more interesting info about which Alpine may work:

Bas,
In the US I have a 91 Sovereign (I believe the same as XJ40).
I bought an Alpine CHM-S620.
Plugged right in, cranked right up.
The Plug in the trunk is an 8 pin DIN. It’s about the size of a US Dime
in diameter.
I do understand that some of the later years may need an adapter, but
mine did not.
Good Luck,
Ken

Bas,
My ’96 XJ6 also took an Alpine CD, and, although a $75.
adapter cable was needed, it still was much less expensive
than the Jaguar dealer wanted. The Alpine dealer claimed
that the OEM CD is made by Alpine. I wouldn’t know about
that, but I do know that I am very satisfied with the Alpine
CD. also bought 4 extra CD magazines (2 for $30.), so
I can rotate among 30 CDs, and change the selection as I
want.

Here are a couple of informative posts from the Win in the Jag-Lovers archive - Win is one of the experts there. He posted these in the XJ40 forum but as you will see he also refers to his '97 X300:
JagFORUM Logon
The only functional difference between the chm-s630 and
chm-s634 that I know of is the later unit will play mp3's.
The chm-s630 will happily play cd's, cdr's and cdrw's.
Unless you are looking to stuff several thousand songs into
the changer, the chm-s630 should do what you need.
As I understand it, the later models mostly just added
additional formats. The earliest ones are pretty fussy
about only store bought CD's. All pretty much use the same
suspension and have similar audio quality.
I've not had any luck finding a ''definitive'' breakdown
between models. My '97 has a chm-s601 in it and even it
will play most of the cd's that come off a computer.
JagFORUM Logon
Any of the Alpine CHM-S6xx changers will work except for the
RF units.
The CHM-S634 is probably the most desirable as it will play
MP3 formatted CDs and you can stuff an entire library on the
6 disks but all from the early CHM-S600 to the last CHM-S634
will work.
Cheers,
Don

And here is another one, that seems to confirm (in an obtuse way) that the Alpine changers in the Jags are the older M-Bus changers. But since there are conversion cables to support later AiNet changers, one could conceivably install the latest changer. That would have to be tested, but I suspect it would work.

If you opt for the AiNet version, the CHA-S634 or another AiNet changer, the following cable converts from M-Bus to AiNet connectivity:
Alpine Ai-NET to M-Bus adapter,
Alpine part # KCA-130B
From: http://www.nsxprime.com/FAQ/DIY/Alpine-S634.pdf
Bottom line, a quick Google seems to find a lot of other car manufacturers that used M-Bus Alpine changers, even with other HK systems. And a lot of folks have retrofitted the changers with Alpine units.

Be advised that the software in the later radio head units are NOT compatible with the ALPINE changers anymore.
I had a customer in the Jag dealer back in early 2000s that had a factory reman radio installed in his X300 and the ALPINE CD changer no longer worked.
He was pretty upset so I showed him the TSB and he told me to remove the radio and reinstall the original.
He ended up having the old one repaired so it would recognize the ALPINE changer.
Just a caution!!!!!

I Drive a 95 3.2 X300. I can confirm that my Head unit and CD changer use an 8pin M-Bus cable. After doing a lot of research on the topic and trying Alpine M-Bus to 3.5mm and such cables I can also add to the topic that, these units use a specific Alpine Protocol that identifies the head unit to the changer. This is the source of the problem with the head unit not recognising the CD changer. It is also the issue that makes installing any kind of Aux device very problematic. I emailed my Local Alpine service centre hoping they could repair my changer or offer an AUX plug'n play that would allow me to use the CD changer input for an MP3 player or Smart Phone. I never received a reply.

I've been searching the web for detailed instruction on the "soldering" fix for our changes, that are not recognised by the Alpine head units. The closest I could find was a brief description and photo
Jos Raven PA0AMX
From the photo and description, though, I'm now unsure whether the problem is with the Head unit or changer?
As for the "No Disk Error" and worm wheel adjustment, there is a great description with photos in PDF format here on Jaguar forum. com, but will repost the link to make it easy to stumble across.
