Hello, I’d like to retrofit the Combox module in my E60. It can be done and it works well with proper coding. All can be found on the Internet. However every guide is about swap from TCU, MULF2 High or simultaneously both of them. I have the MULF2 (not High) only. My VIN says the car is equipped with the S644 option
(Preparation F Mobile Phone W Bluetooth).
Is it possible to do the retrofit? I’m not sure about the pin outs in guides. I know it’s needed to buy:

• BN2000 Combox unit
• stuff for the harness that must be selfmade
• the USB/AUX hub with cable to route it to the armrest

Anyone did this combox retrofit with the car configuration described above?
One more question: is it true that if my CIC software version is the C16 it doesn’t ask me for the FSC code? About this retrofit the main goal is to have the A2DP Bluetooth streaming and the ConnectedDrive with BMW Apps.
Hope you will help me.
Love 😊
