"No Microphone Connected"? Bespoke HU, need Plug Diagram.
 

Howdy yall.

I just got my car back from the dealership (had to replace the whole wiring harness since they bork'd it somehow from replacing my fuel pump. took over a month!), and I've been finding all sort of little issues they've caused while screwing around with my car.

Apparently they've f'ed up the microphone, only god know's how, so now I can't place outgoing calls via bluetooth. If I initiate calls from the phone, folks on the other end can't hear me until I take it off bluetooth, so I know they've either jacked up and broken some wires, or they didn't fully seat one of the connectors.

Does anyone have a diagram of the back of the stock bespoke headunit? Need to find out which wires are the microphone wires, so I can use my multimeter and see where the problem is.

Thanks in advance!

Why not just bring it back to the dealer for them to fix if they broke it?

No confidence / no time / don't want them to cause another issue / I'll then have the knowledge for future reference. Pick a reason, they're all just as valid.

Anyone? Been googling diagrams, but haven't found anything for the plugs on the bespoke.
