Retrofit Bluetooth with a TCU instead of a ULF in any I-Bus Car

hello guys,

i would like to have bluetooth at my 06/2002 Euro E46 and was searching for information.

what i found out is: i should have the second generation phone wiring as my car is produced later than 03/2002 and i have BIT2 phone.

so it should be plug&play to buy a ULF and use it instead of the BIT2 hardware.

but, i came across that i already have a bluetooth antenna under the ash tray as my car also has bmw assist.

doesn´t this mean that my car already has a TCU?

galaxy s2 couldn´t find it, should it?

am i right, that i could buy a GSM TCU with bluetooth support (which p/n is the first with bluetooth?) and just change the tcu? do i have to unmount the BIT2 completely?

just to be more precise, i will add the options list from my car:

Quote:

SA601 Analog TV
SA609 Navigation system Professional
SA612 BMW assist
SA620 speech input system
SA630 Car phone with cordless receiver (BIT2)
SA672 CD changer
SA674 Hi-Fi system Harman Kardon

any advice is highly appreciated

I'm not very familiar with the BIT2 system, but doesn't it use bluetooth to talk to your cordless headset?
If that's the case, hopefully your bluetooth antenna cable (FAKRA style) will plug into the bluetooth connection on the new TCU. If not, you may need to remove the plastic casing around the FAKRA connector in order for it to plug into the TCU.
