I have dension 500S BT and also want to convert it to OEM microphone. Anyone know how to convert?

Also, does anyone know where does the OEM microphone connect to (the 2 pins)?

Mic Wiring

I have a BMW Mic I'm installing, the same listed in this thread. I saw there wasn't complete information so even though it's old I'll fill in the missing information.

1st shine a light inside the connector & you will see each pin is numbered. With the mic down & the steps going up & left to the roof-side of the mic the pins are 1,2,3 with 1 being closest to the steps.
Pin 1: Mic +
Pin 2: Mic -
Pin 3: unnecessary, but connects to the shielding on a shielded mic cable & to grounding or ground pin at the other end.
I have not installed this myself yet, as I'm still looking for the connector end to use for my install, but I have the information definitively
