Edit: I forgot to put in a big THANKS for sharing your project and inspiring me to take up my own! Really appreciate it!

Since you integrated a 3.5mm jack on your pcb I guess you have a pretty good idea how to connect this?

I just ordered a RN52 (although on a breakout board, going for a easier solding job..) and I guess there is need of an extra circuit to change from single pin to differential input?

What do you mean with "you can switch the pins to either high or low level"? As I understand it MIC_BIAS is used to pwer the microphone, and I guess we should go for active then? Or does that depend on which microphone that is installed in the car?
