Questions about the phone, TCU and Bluetooth
Hi guys.
I live in Sweden and I bought a BMW M3 E46 2005 from USA. I'm having big trouble with the phone and bluetooth. I have put Swedish simcard into the TCU (both slots) the one on the side and the one under the plate inside the TCU unit. I can read the phonebook and my contacts on the simcard but I'm not able to make any calls except Emergency call. The red light is ON and the yellow light is blinking. Can it be that this TCU only accepts simcards from USA? Do I need to change it to TCU from Europe or something? When I go into "info" I can see that I have no strength with the simcard. The simcard is working on regular cellphones. I visited a BMW shop and printed out this information about my car: (Complete PREP. Cellular Phone USA/CDN) About the bluetooth function.... I would like to know if my car has bluetooth or not. When I tried to connect my phone with the car then the phone found this device on the car "BMW89722". I added it into the phone and typed in the same code but nothing else happened after that. If I search for handsfree devices then the phone cant find any. My TCU looks like this one: http://i833.photobucket.com/albums/z...s/IMG_0730.jpg I also have this phone in the car: http://i.ebayimg.com/18/!CFWyUQ!B2k~...u!21w~~_12.JPG I read somewhere that I might need navcoder to activate bluetooth? Is that something for me? But how do I know if I have bluetooth? On the TCU it says Bluetooth and I also have the code written on it but how can I be sure. I be greatfull if you guys can help me out because here in Sweden not many people are familiar with these problems (not even BMW) so I hope you can spread some light here. The main questions are. How can I get the phone to work, so I can make calls. And how do I use the bluetooth if I have it on the car? Regards Kim

Your TCU does not support Bluetooth handsfreee, even though the sticker might say BT on it. After Q4/2004 BT handsfree was added. Before that the BT was used exclusively for WDCT handset.
You may not be able to use your SIM as the network might be 3G only. Does your network support GSM 800/1800? US TCUs are usually CDMA2000 (without SIM card). Yours might be GSM850/1900. Are there any marking indicating if it is EU 900/1800 or US 850/1900 GSM on the TCU sticker?

Based on the model year of the car, if it had a factory TCU, it would have had Bluetooth. However, that module was likely added after the car left the U.S. The TCU modules in U.S. cars did not have SIM cards.
You will have to get the exact part number of your TCU module and then research if it has the Bluetooth function. My guess is that your TCU does not support Bluetooth. The plus side is that adding BT is a very easy retrofit in your car. It is pre-wired for the BT-enabled TCU, and it is plug-and-play.

Here you can see how Stringback got on with the SIM version of the TCU.
I agree with Brian-BMW the car was probably converted to WDCT after it left the States. Why it doesn't work with your SIM could be you have a 3G only network. Again, all will be revealed when you post those pictures of the TCU stickers.

I could not find any difinitive information on that part number. However, it appears its date of manufacture is in September 2009, which makes it aunlikely that it has Bluetooth. Plus, I do not see the Bluetooth logo on the part number sticker, which is usually present on all BT modules.

so what kind of simcard should I use on this TCU? A simcard that support 3G? The simcard that is inside the TCU support 3G but I dont get any strenght when I enter "info" on the options. I can call some of the companies here in Sweden and ask them if they got any specific simcard that works but all I need is some info about what I should ask them.
About that bluetooth kit. Where can I find one and buy it? Is my TCU BT-enabled?

OK so you have a 2004 WDCT TCU. It has a 2.4GHz radio (cream FAKRA connector) that you can't connect your BT phone to. The TCU should work in Europe with 900/1880 SIM cards. The SIM inside the TCU is for BMW ASSIST. The sim in the cradle or in the TCU slot is for the WDCT handset. Here in England if you buy a THREE (3G provider) SIM, they share the 2G network with Orange/Tmobile for 900/1800 coverage.
Anyway, this is old technology. Since you have the 54 pin connector you can swap your old TCU for a new TCU or ULF.  The TCU and ULF software and hardware got better as time went by. The last ULF was a GEN13. The last iBus TCU rolled out in the 2008/9 X3 facelift. Do not get confused when browsing eBay. After the E46/E39/E38/X5 Mk1/Z4 Mk1/X3 Mk1 the TCU went to optical fibre, and it gained a second connector next to the 54 pin one, and is not compatible with your car. Pros and cons: The ULF has voice control for the phone and Nav The TCU has voice control for the Nav only The TCU apparently has a better ring tone than the ULF. The ULF needs a pairing button or eject box, the TCU does not. The EU ULF appears to be quite tricky to pair in a retrofit.

Just bought 2008 X3 from USA. There is a TCU in the car. Is it possible to use this system in Europe with Nokia 6700 classic? Thank you.
