When I added my Homelink Module last summer I thought this thing that was inside the sunroof switch panel console
(shown in the picture below) was a prewiring connector for the BMW SOS/Assist Switch. Turns out that no E46 cars have any prewiring for a BMW SOS/Assist Switch. So I assumed it was a switch for the BMW Bluetooth MIC....
Here is the problem...today I started doing my BMW Bluetooth Retrofit DIY
and to my surprise the MIC connector looks nothing like that...
it looks like this (the black 2-3 pin connector).
So what is this thing? What would it possiblly connect to?
