Haha, you should see behind my dash with the wires, it's a mess!!

I haven't tried playing with the mic bias, I don't remember seeing a command for that on the rn52 datasheet, but I could be wrong.

I did find one site where an actual electronics person tried to get a different mic working, and she had her own problems. Her solution involved a circuit which I haven't tried yet. Here's the link: http://www.jenrathbun.com/Electronics/rn52-bluetooth-adapter-microphone/

my top console is still dangling wires, since I don't know which impedance we should be using...still more testing that needs to be done in order to try and figure out how to use this stupid mic. I think that we need to try playing with the MIC_BIAS line (via software) for one, and two, maybe see if we need any more circuitry (I saw something in the RN52 datasheet about the mic needing a high value resistor to ground on the mic line if the impedance doesn't match...?)

If neither of those work, then I'm at a complete loss how to get the Saab mic to work.
