Factory mic wiring into android head unit

[Brad_e92]

Hi everyone,

I have a e93 M3 and I would like to take the wire from the stock stereo and solder it to a jack for use with my android unit. Can anyone tell me what wire this is on the back of the stock stereo? Or where I can find the end of the mics wire?

Will what I'm doing even work? Has anyone done it?

TIA

Not sure if that will work. Not sure if there is a mic input jack for the android head unit. And if there is, why not just buy a cheap microphone rather than butchering the stock one?

I have an android unit in my car and I still take my calls thru original iDrive. My phone can pair to both devices at the same time - iDrive for calls, android head unit for media audio and Waze.

Ah so I just can't stand having extra microphones and stuff about the cabin I like to keep things looking oem. Mine does have a mic jack input
. And if yours doesn't you can buy a different harness or if your good with electronics you can pop the back open of the android unit and there's two contacts you can solder too for a mic.

The issue is I use my head unit with apple car play/android auto so it all gets overridden and sent there

Ah OK. The easiest thing to do would be to just get an aftermarket mic. Keep the stock mic where it is in case someone else needs to use it.

I think what you are looking for a is a mic splitter cable. They come with some carplay/android auto kits, but can be tricky to locate separately. You can cut the 3.5mm connector off and solder it to whatever you want.

As far as I know the microphone doesn't directly connect to the CIC/CCC head unit, but connects to the combox in the back. The design was simplified in later bmws, and the microphone directly connects to NBT/NBT Evo head units.
