Depends - if you have the TCU-ECE model, and it came from a car which previously had the cordless DECT handset then some settings may need to be changed.

NavCoder is your friend :-)

Neil, Can you post the changes you needed to make to the connector? As in what colour goes to what pin?

Cheers,

Ha good sales pitch :) I'll be buying it shortly as it definately wont pair :(

Not that easy mate. Depends what your starting with and what your going too. Plus cant get mine to pair yet so not gunna tell other people how i've done it as may be wrong

Well, give us a chance, I'm doing exactly as you, going from a cordless Siemens in a RR to a BMW TCU. I'll give it a try and see if mine pairs.

Ok at the moment its 15 pages of scribbles, and diagrams. Let me get it typed up so it's understandable and you can have a go.

can you help me...?? i buy yesterday a used 10/ 2004 x3 2.0d with nav.i checked that i have a tcu 84.109129850-01. but i can not pair the phone.on the screen of the radio-nav i only have options like computer-sat nav-set and monitor off (if i remember right) .i can not find any option about telephone.what i have to do??

If the "Telephone" option is not displayed on the main navigation menu, then the TCU is either not connected or it has failed. Based on the date of manufacture, that TCU should have the Bluetooth feature, but I am not as familiar with the European TCU modules.

yes on the top of the tcu has the logo of the bluetouth and a 4 digit pk.it is like this one http://filer.case.edu/jxw115/BMW/BTO.../img_1131a.jpg

Check its plugged in firmly and that the fuse isn't blown. If the unit doeasn't have power, the car wont know its there.
