Factory fit BMW microphone 1OHM 3.5MM
Featured positive reviews:
Installed a Sony XAV-AX100 in a 2005 BMW E46 325xi with the below equipment mounting kit by Enfig Car Stereo. Mic fit perfect in the slot, snapped right in, on the section were interior lights are. And it works great, nice and clear, callers can hear you well. May want to have instruction on how it snaps in because it was not on the video.
