NavCoder is your friend :-)

Jochen - Another puzzle for you - why is the BT Pairing button greyed out? I cant get my phone to pair (TCU doesn't appear in list of available devices) and i thought navcode could be used to force pairing

In the latest Beta version your TCU gets identified as a TCU-GSM

I do not know of a way to initiate bluetooth pairing mode programmatically on the TCU-GSM, hence the BT Pairing button is disabled.

But talk to me via email for some fun things to test with your TCU :-)

Do you have any idea why i cant pair? My phone doesn't find the car, i try just after i switch ignition on, i've enabled bluetooth, but nothing. This is the TCU i have retrofitted into a Range Rover

Did anyone have probles getting a TCU into pairing mode? Some people in this thread report the need to plug in the eject box temporarily to get pairing to start.

It is possible that a European TCU uses the pairing button in gibbo_ireland's situation. Or, it is just as likely that gibbo_ireland had a ULF and not a TCU. I vote for the latter. Every BMW document I have read and everyone else's documented experience I have read states that the TCU goes into pairing mode every time you start the car.

Can't say I recall where I found this file last year... but for those who have an account on BMW TIS EPA, here's a decent list of Group 84 (Communication) SIBs. Perhaps this could help in some troubleshooting. Most issues have to do with Assist, but there are a few on Bluetooth pairing.

Maybe this extra step is required?

1) Turn Key off and then to KL-R or KL-15. 1.
2)The vehicle is ready for pairing for the first 2 minutes of key on. 2.
3) If the R/T button on the MFL is pressed, "Activate Phone" appears on the MID or Board Monitor. For the E53 X5 the seatbelt needs to be plugged in and the R/T button pressed on the MFL and "Activate Phone"
appears in the Instrument Cluster.

Press the "R/T" button on the steering wheel emulator in NavCoder

I logged
20/03/2010 11:58:23.881: 50 04 68 3B A0 A7
20/03/2010 11:58:23.881: MFL --> RAD : Radio/Telephone control: Send/End_released

I think I need to try it in the car, if it ever comes back from the mechanic...
