audi mmi 3g high coding

[mike870]

Hello, i have done a retrofit on my a4 b8 from basic mmi to 3g high mmi, the donor car had B&O subwoofer and the 5f unit and the 56 unit radio is coded on B&O amp and i have no sound with my standard audi dsp , the 2 units are on most , no fiber optics erros, if i change the 3 byte coding from radio unit i have sound on the internal amplifier but no sound on the external system, where is the B&O system coded ?

Thanks,
