Hi all,
I've had my red '02 CD 2.6 V6 for just over a week now and I'm starting to get to grips with it. No major issues, just a couple of little things, but I'll post them elsewhere.
One question I have though - I've got a Motorola HF850 Bluetooth kit (they are now going for as little as £19.95 on eBay) - my wife has been using one for some time now, and they look pretty good. My Omega already has a Nokia car kit, but it has been fitted badly in my opinion - it uses a tax disc aerial, no radio mute, they have drilled the console, and it is powered from the auxiliary power line. Now I know that my Omega is one of the models with telephone prewiring, as it is the right age, has the antenna on the back, and there is the 18 pin VDA connector behind the glovebox. I used to fit PMR equipment to cars back in the days of the Senator, so I'm okay working on car wiring looms - The Motorola connections are subtly different to the Nokia kits, so I'll have to modify an adaptor lead or make up my own. My question is - I've been reading about this extra relay and/or transformer that is required by some models - can anyone tell me if mine would already have that fitted, or would I need to get one - and if so, where does it go? - the stereo unit is the 2005 single slot CD player.
Thanks in advance, Glenn

Hi,

I'm just about to fit a Parrot CK3100 to my car (mini facelift), and have got the multipin wiring all prepared for when the Parrot arrives - subject to postal strike.

As I need to list out the connections I'll happily let you know what colour wires do what.

I did this before when I had an Omega new many years ago as a company car - so am quite happy that this is a route that I've been down before. I don't have the coax on mine - but don't need it as using Bluetooth.

The "relay" isn't a relay its an audio isolating transformer and uses the twisted pair of the multipin. If fitted it will be up underneath the steering column and is a REAL PIG to get to. If your car has the roof aerial then it will have the relay in place already. Mine only had the multiplug - so no transformer - getting hold of one was easy enough (scrappy), but plugging it it was, well, painful!   

Basically, when the mute line gets grounded the audio system takes the (mono) inout from the transformer and plays through the stereo. It works even when the stereo is switched off - turning it on when the mute is grounded.

The input level is set for the audio can be adjusted (on the min facelift anyway) on the stereo, although from memory I recall this aspect being the one that caused me the most headache at the time and had to fiddle around to get it right.

HTH and will provide cable functions if neeed.

Regards .......... Rob

Thanks Rob, that makes sense now - I guess the matching transformer stops any input from the 'phone kit damaging the other circuits.
Yes, if you could let me have the pin out for that connector, it would be great  - thank you. Good luck with the Parrot - I'll let you know how the Motorola goes....
All the best, Glenn

Will do, it all depends on when the postman arrives as to when I get stuck in as I'm not removing the glove box unless I need to!

bluetooth kits don't usually need any kind of aerial - as all that happens is the audio is bluetoothed back to handset, which uses its internal aerial.  Not ideal, but thats the way it works.

The prewiring plug, assuming it hasn't been butchered by previous install, provides the 4 power/mute related connections that a standard Nokia kit requires (note - you must put inline fuse between this prewiring plug and your equipment on the 12v and on Ign 12v wires!), and the connection to the stereo's audio in. Some (but not all) provide the wiring to the mic, but not all cars have the mic.

It is all very easy - the mic and speakers are easily found on the connector, as they are coax. The other 4 - 0v, 12v, ign 12v, and telemute - are easiily found with a meter.

The cellular aerial, should you need it, only goes as far as drivers kick panel - you will need to extend if necessary, and its not an easy route.

The mic cable is thin coax, the speaker connector to the isolating transformer is actually a twisted pair and easily identified.

Some factory fit Bluetooth kits do have an external aerial connection, but require model specific phone adaptors/holders which provide the connection to the aerial. However, these are usually in BMW/Audi zone and the adaptors cost between £50 & £100 - on top of the £350 to £500 cost of the Bluetooth install option.  :-/

Thanks both - the HF850 does not have an antenna connector, so I won't need that (My Motorola V9 does not have an antenna output anyway), although I do see it there. The HF850 does have a speaker output, so I'll put that across the transformer - I'll experiment with the vauxhall mic, as some people say it's not so good - I don't mind running in the Motorola one.
Hope the postie turns up! (and mine with my HF850)!
Cheers, Glenn

What you could try is using the pre-installed Vauxhall mic coax cable to extend the Mot supplied cable.

Ok, you have a two splices, but is that really a problem as the Mot kit then gets to work with the mic supplied with it.

[TheBoy]

There are 2 type of mic for omegas, those without built in preamp (suitable for nokia kits) and those with preamp (suitable for NCDC stereos).

I believe that facelifts tend to have the preamped ones, prefacelifts have the non preamped ones.

Of course, in many cases, no mic is fitted

[I_want_an_Omega]

That will be me then as I don't have the aerial cable and a normal interior light.

Run the parrot mic direct from parrot unit all the way up to sunroof console. pretty easy route to be honest, not worth trying to reuse any cabling for that

The badly fitted Nokia kit in my car has the Nokia mic run up to the courtesy light panel, however I do see there is a Vauxhall mic in there.... I think the people who installed it did not have a clue - not even getting the power or mute off the VDA connector - I'm more annoyed about the screw holes in the side of the centre console... GRRR

Not uncommon for some of the network approved fitters - some of those are awful
