Great - everything is a lot clearer now.

One last thing thought. What types of telephone module are there?

Obviously there is the ULF module, and the TCU module i need to fit (with bluetooth), but what other ones are there?

I'm assuming my car doesn't have bluetooth, because it has a slot to put a sim card in. But could it be a case of removing the eject box and adding a bluetooth antenna?

I'll have time tonight to try and finde the telephone module in my range rover (in the boot maybe) but i think it will only have Land Rover part number on it

Well there's the Siemens fixed unit, the Siemens cordless phone, around 2 or 3 variants of that
Plus Motorola, around 10 variants

In all there's around 15 or so different phone types for the BMW.

Depends on vehicle, age, country, system...

Nothing is ever easy it is hahaha.

Well had a quick look at WDS, and i have the cordless type, and it's a 2003 Range rover so my money is on the highlighted one in the pic, but i will take out the telephone module tonight and compare wiring colours/pin locations on the module.

Neil, I've been working on preciciely the same conversion. Bimmernav sells a kit to do exactly what we want using original parts but it's pricey. A couple of smart guys like us can certaintly figure it out. So I got a UTF to try but when I plug it into the factory plug it freezes the satnav etc. I have heard that the Range Rover and X5 use slightly diferent pinouts although the same conector. I have downloaded teh pinout for the x5 but haven't found it for the RR so am hoping the colours are for the same components... that's as far as I have gotten.

UTF???

And what connector did you look at? I'll be taking my phone module out the range rover tonight, so will happily share pin outs on the connector that plugs into the module.

Is the telephone module in the boot in the rangie?

Yes, in the boot, around where the video module is.

If you have the Siemens phone then the pinout is shown in the WDS.
But confirm the phone type first

OK this is what i have, I really got confused when i saw the antenna (part number 8540 8387422) ontop of my nav drive, i thought it was bluetooth but not sure now. Also, should there be two antennas? I could see two antenna cable plugged into the bottom of the siemens unit.

Now how do i find the correct one in WDS? And more importantly, if i buy a TCU, how will i know which wires go to which pins if i cant check the pin configuration of the car the TCU came from?

The antenna is the WDCT antenna (worldwide Dect)

[QUOTE=neiloakley;702894]Now how do i find the correct one in WDS?

It is printed in black and white on your phone module what it is. And looking in th WDS, there are only TWO matching options - and the only differences are with or without voice recognition.

So there you go. The phone type is non-ambiguous.

Again, look at the WDS. You will see there are only 2 x TCU entries. And the only difference is with or without voice recognition.

So once more the solution is very clear.

Refer to the WDS, and compare the wiring differences between TCU and your Siemens BIT-II phone.

Then simply change the BIT-II wiring to the TCU wiring.
The WDS tells the whole story.

argh i think it's just clicked. The Wiring is not specific to the unit, but the car.

SO all TCU units need the pins in the same configuration, and it need to swap the wires in my car about to match the configuration required by the TCU

So my car currently has
Telephone (BM On-Board monitor with Fixed mounting, Siemens (cordless handset) with SES Language-input system up to 2002_3)


And I want to fit a TCU unit so i need to swap the wiring to match the following:
Telematcis control unit (TCU-Everest) (SES Language-input system with TCU Telematic Control Unit without USA_LHD)

Which TCU i get doesn't matter, as long as i have rewired my connect for a TCU moduel correct?
