Hello ,

I’m currently in the process of retrofitting Combox in an 09 x6.
I'm looking to repin the connector but not sure if I Have TCU + MULF.
I’m able to see the TCU and the car have 6fl but I can’t find MULF.

Vin: L222811

If anyone can help me with the correct pinout I need that would be great

Thanks in advance.

HI,

car should have TCU for bluetooth speaking and Mulf 2 High for USB function.

BUT a bigger problem should be, that your car has a CCC navsystem from OEM.
So you have retrofitted a CIC navsystem to get the combox working.

I'm looking for mulf in istaD and find it under this middle rear "seat", looks both rear seats have to be removed and than also this middle one part

but CCC not compactible with combox, have to start with CIC instalation

next step - preLCI e70/1 have problem with cic - no PDC image, have to use emulator or change JBBF module.

Great thanks for the info guys!

I’ve already retrofitted cic with emulator to fix PDC/RFK

Next question is do the combox go where the tcu is in the trunk or where the mulf is under the rear seat does it matter?

[jararak]

It depends on your decision. Combox replaces mulf as first option - so TCU can cooperate with combox, or you can get rid of TCU also. It depends if you want to keep SOS/Telematics funcions or not. Idid this on e90 and f10 where you have both of those modules on same plate, but different side, but not this kind it is 1meter between them. If you throw away MULF - you have to move USB wire, if you plug it instead of Mulf, you have to move BT antena and microphone wires at least

try check this one

Hi Jararak,

Thanks for your help so far.

So the combox I got is bn2000 mean it’s the telematics version.

I would like to remove both module (tcu and mulf).

I would need extra wires to reach the combox.

Base on that pin out you link too for this I need to take wires from both mulf and tcu but they did not mention how to do so or even about the usb/bt antenna

HI,

you must remove both module to get a working combox retrofit.
TCU is workign for bluetooth speaking, so I prefer to install the combox to the TCU place and then connect the USB cable from Mulf 2 High to the combox, but you must extend it if I remember me right.
Same is for aux conection - if needed.

Then close the optical fibre cable from most and you can start the coding.

Hi Thorsten,

That is how I plan to install it combox where TCU is and remove MULF.

extend wires/adapter from MULF to combox.

but how do I extent wires? were can I buy adapter?
