My car has a overhead mounted microphone for the OEM Bluetooth phone. I have a tablet installed as a infotainment system and I need to connect a TRS microphone to it. The OEM microphone has two wires. Just wondering is it possible to actually run another parallel cable from the OEM microphone and wire it to a TRS jack and have my tablet share the same microphone? Chances of the tablet and the telephone being used together is very slim but what would happen if both devices was using the mic at the same time?
Thanks
