The G20 has no ASD module as in the F30, therefore it cannot be coded off as in the F30. The ASD feature is now integrated into the Booster - either separate OEM amp for the "acoustic sensor" speaker or the Top HiFi systems.
No more engine sound mixing with the music either. The ASD feature has its own speaker - the "acoustic sensor". Therefore, unplugging the speaker should stop the engine sound.
