Rarjar,
I saw that you were trying to use the OEM Mic for your bluetooth, did that work ok? Good sound quality etc? and did you figure out if you needed to use pin 7 afterall?

Qoute:
"OK Tox, I found the connectors for the OEM microphone. They are on the K9 connector... Pin 1=MIC(-), Pin 2=MIC(+), and Pin 7=MCVD. What the heck is MCVD? I assume I only need to use Pins # 1 & 2 and can ignore Pin 7?"
