BMW F20 MFSW buttons dont work

[brunorosaa]

Hello,

I recently add a MFSW to my F20 that does not bring from factory any buttons on steering wheel.

I code the FA with the code 249 and 544.

Now the volume up and down works like a charm, but when I receive a call I cannot answer it from the steering wheel.

What am I missing?

I do know that for the CC work I need to change my cluster.

Best regards,

Bruno Rosa

Just an update on this! 

For the steering buttons on the right side to work (mode, telephone, and voice) I had to code the HU_NBT with the FA 249 and FA 544, because the car was no buttons from factory.
