I still don't have mine working, I have been messing around with coding the vehicle from time to time and have added the 633 option, but haven't been able to delete the BIT II option. I think I need to find someone with a power supply to get the voltage up to allow me to go any further.

Would you advise against buying a tcu then? I have a NZ new E39 with a fitted BMW phone (Sim Card). I am looking at a TCU the same as yours 84109129850.
I have a working GT1 as well as Navcoder ect.

By all means buy a TCU, but get a late model CDMA one from the US. Not the Euro GSM one that I bought. The USA ones seem to be easy to get going. However I can document the pin changes for your cables to convert from BIT-II to TCU on the plug that connects to the unit. The Wiring in our AUS/NZ cars is a little different

Thanks mate, i would appreciate the pin changes. Jochen advised me to opt for a Euro GSM TCU and not an american one. However your problem leaves me in two minds.

Also FYI I dont have the Navi unit like you, just a BMW Business RDS with MID so that might have something to do with your problem? Although I dont really know why. At worst case it will be a good test.

OK, Jochen is the man, but still, to my knowledge this thread is the only documented BIT-II to TCU conversion on a Euro spec car that has succeeded and using the USA ones seem to be a common conversion. Jochen's on NavCoder supports the CDMA one well, the GSM one to a lesser extent (e.g. the pairing button works in the CDMA one only). The GSM (or CDMA) part of the TCU isn't used, all you and I want it to do is make the bluetooth work to the speaker and mic and the buttons on the wheel work. I will document the pin outs and post them here in the weekend.

I suspect my problem is that the BIT-II and the SA-633 Euro TCU use overlapping iBus commands (or unit IDs) and thus we need to delete the BIT-II in order for the control software such as INPA to see the unit correctly.

But who knows.

It is not an issue of overlapping ibus commands.

Both devices are a telephone, and both devices have the same bus address TEL. Hence only one device can exist in the vehicle (ie be connected to the bus) at one time

If you won't be using the assist function including emergency calls, then you can ignore the phone module inside the TCU and fit either the GSM or CDMA version.

Ok, I have an update, I am still waiting for the cable which runs from the TCU to my bt antenna, but!

I have installed the TCU.

Initially it said "Activate Phone", so I "retrofitted" the module with SSS Progman v32. Which returned as successful.
There is now a red flashing light my MID display next to the TEL button, and the cluster says "please wait" if I push the tel button.
I then used inpa to turn on bluetooth and clear the error about the antenna not being connected.
I figure there is no point worrying about anything else until the cable turns up so I can actually connect the antenna but will let you know how it goes.
