Incoming audio is better for sure. Outgoing audio can be hit or miss, but ultimately I know the right combination to make it work.

Most of the time, the factory mic in later build E46s and E8xs works fine (part ending in 762), but other times it can pick up an echo of the caller which is annoying for the other party. This can be tuned out usually, but at the very worst switching to the microphone with P/N 84318380338 is the final solution. This microphone performs perfectly with the BlueBus.

Thanks!
