My 2002 E46 M3 has that button on the steering wheel. And officially, BT is not supported on the 2002 models.
IIRC, the code is on the ULF module. Looking for the pairing button was easier than pulling apart the trunk to see if the ULF is there. But if the car automatically goes into pairing mode, use your phone to see if it sees the car. THEN, you can go look for the pass code on the ULF.
