Re: What is it? - My guess...

I have an '88 560sel and a gray market '83 380se and they both have it. I have ready that the stereo (on the 560 anyway) had an automatic volume control that would adjust the volume to the noise level in the car. To do that, it would have to use a mic (unless its assume RPMs = Noise and takes it off the tach).
