    Well, I finally did it.

    I effed around and found out.

    I had an aftermarket android head unit installed, and I couldn’t wrap my head around why the external mic wasn’t working.

    I found that other android head unit users got the external mic to function by disconnecting the internal mic manually by severing the internal microphone wires.

    I did this, and when I was putting the head unit back in I guess something was disconnected.

    I know for a fact that a 20624 ribbon connector with 28 pins (inside Android head unit - NOT a Toyota cable) is severed, and I am waiting on the delivery for a replacement cable.

    In the meantime, I decided to put The stock head unit back in.

    The problem now is that neither of the stock nor aftermarket head unit will boot up. Completely dead. I don’t know what’s going on.

    Can someone help me out here?

    I know there’s a 15 amp fuse, a 30 amp fuse, and a 10 amp fuse in various locations, but I have no idea if I’m looking in the right spots.
