if telephone is missing off screen or shaded out then something has gone wrong, best thing todo is to get navcoder it can read the ulf unit and pair it to |

Pin 36 needs to be connected to the negative wire, permanently. Pin 32 just touches it momentarily to pair, i.e. They both end up to ground. Just touching them together won't do a thing.

You have to follow the pairing procedure, not just touch pins. 36 needs to be permanently connected to I think the brown wire, don't disconnect it. Pin 32 needs to go there too, momentarily, to simulate a switch press - I added a Choccy block into the earth so I could just touch 32 to it as needed. Touching 32 to 36 will do nothing if 36 is not still earthed at the same time.

It's alive if you have Telephone in white. I imagine if you press it it says Activate Phone or such like?

32 doesn't go anywhere does it? It's loose, just a length of wire.....

in all honesty I had issues with the pairing thing, from memory once the telephone is white no LED are displayed, you need to put it in pairing mode (I used navcoder) once I got in to it was easy enough

Errr I didn't realise you already had the factory phone - you have to unplug all that if you are using a ULF as it combines all the units into one. Not sure what the car will do with it all still in.

I'm confused, you have to repin the connector to use ULF have you reversed all the pins ? Or.do you have a Nokia hands free system which I believe was quite separate to the Siemen system |

From factory, if the RR has factory phone in the front armrest, it is run by a TCM in the boot. Telephone Control Module. There is generally a Voice Control unit too, also separate. The 54 pin connector in cars without phone is wired to work the TCM. The ULF was never fitted to the RR, only later BMWs, but uses the same connector but wired differently. So when you repin it goes from TCM to ULF pinouts. So you need to repin back to original if you want to use the factory fit handset.
