No paring button, and (special?) TCU...

Hello the Bluetooth experts!

First of all, before creating a new thread I spent a lot of time researching on this forum and others. But I have to admit that I need your help now…

I just bought a used X5. Manufacturing date is October 2003, but this is a new model.
There is a phone preparation with a Motorola hand free set: http://www.realoem.com/bmw/showparts.do?model=FB71&mospid=47739&btnr=84_0513& hg=84&fg=10

The TCU is quite different from the one are usually described here on the board. Mine is at least double thesize, and I think embed the GSM radio part, while the one you talk usually about here are bluetooth modules only. At least, this is my understanding…
Here is a description of my TCU: http://www.realoem.com/bmw/showparts.do?model=FB71&mospid=47739&btnr=84_0543& hg=84&fg=10

I have also the card with all the details (IMEI, PK code, …)
The hand free set works, it just requires to put a SIM card in the dedicated SIM card reader.
According to the Motorola hand free set menus, it connects to the car through bluetooth.

You’ll probably all think that everything is perfect…


Unfortunately, no!

I can’t pair a GSM with the car. There are no pairing buttons (I know the one on the steering wheel can’t be used).
Using a regular GSM (a Nokia 6310, for example), it will not see the car. I tried different timing regardless when I open the car or turn the key on.
Using a iPAQ pocket PC phone (actually a 6915), I do see the car, but the only service provided is “Phone Access Server”. It seems that it does not provide a hand free set profile.

I also tried to simulate a pairing button by connecting pin 1 and pin 2 of the 18-pin ELO connector in the center console, this does not change anything (I read somewhere that when in pairing mode, the 3 leds on the navi screen are blinking. Never saw that).
I did not tried to simulate the pairing button at the TCU side (it’s supposed to be pin 46 to connect to the ground), but I don’t see why I should have a difference.

Do you think that playing with recoding tools would help? If yes, I’ll certainly require some education…
Can somebody with similar configuration (TCU with radio) manage to get bluetooth pairing with a GSM?
Any other good idea?


Thanks for your help,
Lucifer.

Hi,

Sorry to say but it is not going to work based on my, and many other's failed attempts. You need a ULF module in that build date car. I would recommend getting the latest ULF module available as the newer units work much better and support more phones than the older. There are some documents from BMW posted on this forum that DETAIL what newer phones are supported by What newer ULF modules http://www.bimmerboard.com/forums/posts/311138 If you read closely they MAP out the ULF versions with the latests phones. Therefore, it is in your best interest to get the latest ULF modules available.

Hi Ambishop,

Thanks for your reply.
Do I need to add an ULF, or do I replace the existing TCU per an ULF?
If I install an ULF, will the embedded BMW phone (with SIM card + wireless Mototrola hand set) will still work?

Thanks for your help,
FreD.

ULF instead of the TCU. One or the other.

Thanks, this answers my first question, what about the second:

You can only have ONE OR THE OTHER. Not both
