Default Mystery Connector - Can anyone tell what it is?

Hi!

Whilst removing the RNS-D this morning (to get the serial number, to pay for the stereo code), I noticed the following connector sitting forlornly at the back of the nav:



In a previous thread, I mentioned that my centre console night-time illumination didn't work so I was wondering if this little thing had anything to do with it? (not checked David's8's suggestion yet).

Do any of the experienced dash-strippers on here know what, specifically, this connector is linked to and just as importantly, where it plugs in?
I've had a quick look and cannot see a hole for it.

Thanks in advance
Dean

Looks like an after market wire and connector to me. Try and trace where it goes.

Looks like its the connection piece of the 26-way multi plug on the left of this pic, but with its outer shell removed. Did you have anything in that spot?



If that is it, it should have a shell like this on it:

Yes, The black connector with the turquoise lever lock is present. As is everything else in that diagram with the exception of the:
"Brown Ground Connector(not used in Sym II)"
&
"8 Pin connector II"

I hope that having nothing in the Brown Ground Connector and 8 Pin connector is normal. Although I notice that for the AM/FM antenna inputs, I have leads into both - suggesting Sym 1, but the Brown Ground Connector is missing, suggesting Sym II. And David's8 suggested in another thread about missing console illumination may be a symptom of poor ground.
So I am little confused, not being an auto-electrician.

But that connector lead (as in my photo) does seem to go behind the glove box. To where I am not sure. When I am next in the car I will see if I can trace it back without the need to dismantle much. There is a vestigial hands-free mic near the front courtesy lights (left by a previous owner) so that may be the culprit. But there's a lot of coloured wires in it for just a mic.
I shall investigate further.

'Sym' is Symphony (non-nav head units) so doesn't apply here. No ground connector is fine iirc, and Bose systems don't have the 8-pin connector.

I wonder if the 26-pin cable has been replaced at some point in the car's life and the one you have loose is the old faulty one which was just left in place?

To me it looks aftermarket, could be why the Nav needed the code as something else was fitted by a previous owner. The OEM cabling is usually wrapped in fabric tape, this could be going off to an iPod interface or another interface box.

When I bought the C5 A6 that I had before the Volvo I spent a few hours pulling out miles of aftermarket cabling from a cheap DVD headunit with bluetooth and Nav and refitting the OEM radio and also discovering I had no code.
