Integrated mic, aftermarket headunit

So bought an aftermarket android headunit for my car, one of the chinese android ones. This one specifically is a used one i got for a good deal, and was purchased originally from a company i think is swedish, 'Azom'. Them obviously having rebranded a chinese one as their own. Azom MX4.

Because of that detail im not too worried that the specs are false, but their website does state clearly "will not work with integrated mic or aux plug" where they then give you options to buy an external one.

Im stubborn tho, and want to use the integrated one, and have tried doing a continuity check between the two leads on the mic, to the two leads in the matching cable on the PQ connector by the headunit, no continuity.

So does it go via the BCU maybe? And if it does could it work without splicing connectors down there?

Or should i run a new lead all the way up to the original mic? And adding the connector to the end of it, so i can just connect it to the original one. Will that work. There is a PCB on the original mic, so worried it might not.

I am fully aware i 'could just use a different mic in the same spot' and that theyre cheap to order from china, but i am mentally stuck on wanting to use the original one, while using OEM connectors, so it looks like nothings been done, and can be out back to stock easily when time comes to sell it.

I also want to do this with the AUX plug, i assume this one will be easier. But one problem at a time.

Worth noting: i have VCDS, it reports no faults when original headunit is installed, but when aftermarket one is in a bunch relating to a missing radio shows up. And two more: 'mic left shorted to ground' and 'mic right shorted to gound'

Does my car have more than 1 mic? Cause the one mic i know of is mono.

Here in the green part of the plug there is a cable with a white and black lead. This cable matches the one connecting the mic in the other end. Any other leads that could be the mic? No continuity atleast. And I would LOVE to know where the green and black cable goes.

And the 3 leads connected in the blue area, where do they go?
