High Line cd changer

[sworks]

My car seems to have yet another autochanger failure, it goes through changers almost as quickly as tyres... Has anybody got one lying about that works? It’s the standard fit unit with the rectangle plug.
Thanks

Can you give me more detail about the "standard fit, rectangular plug" please, as I'm trying to identify wiring looms, for CD Changers.

First of all, is it an Alpine Unit, or one of the later ones, Kenwood or Sony?

If it's an Alpine, the early ones appear to mainly be a round 8 pin DIN connector, although a black rectangular plug has also been seen.

I guess a better starting point is what year is your car?

Edit, Just noticed your car is listed as a Contemporary, so probably not an Alpine.

Many thanks

It is an Alpine unit and a 2005 car. I thought all Alpine changers off the shelf for aftermarket Alpine headunits were one of two round connectors, mbus or Ainet. When Alpine headunits were used with a manufacturer the connectors were dedicated to the manufacturer ie rectangle for 75’s. I can take a photo tomorrow. Iirc there are possibly choice of two different sub looms that convert from the BMW audio connector to iso for the highline kit. If you try a search there were quite a lot of posts in years gone by with part numbers listed. Maybe rayKay can help?

Thanks,

I have gone back to 2006 or thereabouts, on the forum.
Certainly some relevant questions, but most were not fully answered.

My quest is upgrading Harmony to Symphony (simple from e-bay convertor plugs) then adding in steering wheel controls (simple, and fully understood) but then adding in CD Changer (WIP)

You are right, in that there were two (or more) looms

Factory fit - several permutations, with no "spare" connectors. Part numbers largely not yet identified, but only found on scrap cars, so not too important.

Dealer fit- VUL 100330, Lucas made loom for MGR, accommodates all permutations (CD, Telephone Mute, Navigation) unused connectors acceptable, but No Longer Available (Rimmers)

Would be nice to spend 30 mins. with one, to record all pinouts.

Regards

If rayKay sees this post he might be able to help. If I remember correctly audio was his thing at Longbridge

I'm quite committed today. MoT tomorrow.
If rayKay comments then fine, if not I'll PM him tomorrow afternoon. He sounds like he will be able to help.

In truth, nearly all the pinouts are on the forum, and I've collated them onto paper.

The one I'm not sure about is the black 10 way AMP connector, populated with 8 wires that connects the CD changer's interface back into both the Symphony Blue 10 way, and the MGR round pin main loom. I know all 8 signals, but not certain of their pin allocation. K-bus being the critical one.

I've already been informed that on the VUL 100330 loom that the K-Bus signal has a solder joint embedded in the loom, such that it is a 3 way connection, as opposed to point to point.

I'm also beginning to wonder if the interface was only a separate box for early changers, and became integrated for later models.

The interface is quite complex (I've opened one up) and contains I think, D-A convertors, which is logical.
It also contains a RISC chip. (RISC = Reduced Instruction Set Computer)

Again thanks for your input.

Still after one...
