Chris, I can't locate a mic for the Nokia so i'll leave you to sort that one.

I've got some old Prefacilift autochanger looms winging their way to me (Thanks Lee4206 and Dodger) so will carry on with the loom as soon as they arrive.

Thanks chaps....

I suddenly have a little interest in this topic I'm assuming that a car fitted with telematics will already be using the pre-wiring? So to fit a nokia kit (I have the correct auto-leads) I would need to splice into the telematics loom?

There's certainly no plug taped up under the glove box with 2015...  ANDYYYY. ..... CUSTOMERRRR.

Nah... I'm not gay enough to want to move it

Don't you start, it's bad enough fighting " him" off...

ISTR that the shouty bloke says to use a TM loom, but surely if I have the correct auto-leads product it would make more sense to splice that into the telematics loom so I can utilise the OE mic?

Ooh... Now I'm thinking about it, I could try and get hold of the correct plugs and make up a nice little "splitter" so it works right. Does the pre-wired bit plug straight onto the rear of the telematics or is there a length of cable there?

breaked if I know mate 

I'm sure somebody Andy/TB know...

Dont think you can share mic, hence gayboy will have a seperate Nokia mic for nokia kit.

Not sure if its a straight splice into loom due to impedence issues...  ...might have to play with either yours or gayboys...  ...shame, got enough stuff here almost to test, except non of the 4 telematics units work

[VXL V6]

That'll be three of my units then!!!! 

Just to clarify, prewiring for phone if fitted to your vehicle  will give you access to +12V, +12V switched, 0V, MIC connectivity (clarification of MIC installed in courtesy light required), Audio in (Mono line in to Head Unit) and mute.

In order to run a Telematics you will need CANbus connectivity, Diagnostic link connectivity and I prefer to feed a decent gauge cable direct from the 12V and 0V line into the headunit that at least matches the cross section of the double 12V and 0V lines to the Telematics. This and the ability to not mess with the cars own wiring by creating a sub loom is the reason why we prefer to build these looms using a Trafficmaster loom that sits between the car wiring and the head unit.

I've got hold of another pre-wired "socket" and loom from a breaker (cheers Albs!)

My theory is... Splice the "new" pre-wired socket into the existing car Pre-wired connection (currently plugged into the telematics unit) to give a "spare" pre-wire connection, then plug the Autoleads 109 (right one) into that socket. :-/

At the end of the day it'll cost me peanuts to try it out and it may be the tidiest option :-/ :-/ I really need to look at some wiring diagrams but don't see any reason for it not to work properly... Only issue I can see is if there were to be a call on both phones at once :-/ :-/

If it doesn't work, I'llTB/someone can knock up a modified TM loom for me

But surely if I have the correct telemute lead for the car, with the special box of tricks, then it should plug straight in? :-/ :-/

As in, I could unplug from the telematics and plug the telemute lead into the pre-wiring and it would work... I'm just splicing into that to give the dual phone capability :-/ :-/

It's not a problem to run both Telematics and a carkit together and it will work if both receive / make a call at the same time.

Your method of splicing a prewiring socket into the corresponding lines of the telematic loom will also work, though you wont have a Mute line on a genuine Telematic Loom as this is handled in a different way. 

The issue you will have is that you cannot use the same microphone as the Telematics one is different to the standard one and you may also find you have an impedance mismatch on the audio in lines.

The big question here is what do you currently have? A facelift vehicle with the full factory NCDC2015 / Telematics setup or a NCDR1500 / Telematics and a loom to fit this to a prefacelift?  :-/

What do I have? Errm... Shhh... It's a secret! (but the former applies!)

My understanding was that you could plug the correct telemute lead into the pre-wire socket and everything works ok :-? My intention is to slice into that, creating "twin" pre-wire sockets, one for the nokia kit and one for the existing telematics ... That way both of the pre-wire bits on the car will have all of the connections (although, to be fair, the one for the nokia kit I would only splice the required pins).

The telemute lead I have is the correct, supressed one so should be ok for speaker outputs :-/ Just the mic that's in question... But if the telematics wasn't there and the nokia kit was plugged into the pre-wiring it would work with the fitted mic... So it should work fine :-/

[VXL V6]

Right, think I understand, however, the inbuilt prewiring in the car does not support Telematics, that requires some extra lines not present on the prewiring plug. If you wanted to add those extra lines (listed on one of my posts above) then I guess you could as there's plenty of blank spaces on the prewiring socket.

The Telemute / Autoleads adaptor with the matching transformers does not cure the impedance issue when a Telematics is introduced to another phone, they are there to ensure that the Bose amp doesn't make a bid for Bose heaven (supposedly) - or as Autoleads put it 'to save issues with Bose'. The Jury is still out as to wether they are really required. On factory fitted Telematics installations we believe there is an impedance matching device somewhere (shown on TIS diagrams), the circuit TB made up equates to the same solution.

Simplest solution to the MIC issue is to use the correct MIC for telematics in the courtesy lamp and the supplied kit MIC for the car kit.

Remember also that Telematics is paired with the HU and Screen and therefore I think the HU may get a little upset if it's not present 100% of the time.
