Hi does anyone here have wiring diagram or photos how is oem bluetooth microphone wired?

2011 octavia with swing radio and bluetooth

 

I would like to use oem BT microphone with aftermarket chinese android unit.

I think it goes to under the driver's seat. Don't think it does to the back of the stereo. Should just be a 2 wires + & -

 

I didn't have an OEM microphone so I bought a Fiscon that fits I to the OEM slot in the interior light but has a standard 2.5mm socket that plugs straight my Android radio.

 

 

As Phil-E mentioned, with a Swing and BT module, the mic will likely go directly to the BT module.

 

At a guess:

- BT module: pin 11 mic +

- BT module: pin 12 mic -

 

The only exception would be when a RNS-510 Columbus with voice control is fitted. The mic would connect to the headunit then there is an extra pair of wires between the headunit and BT module
