This is a brilliant solution, but I'm not brilliant enough to divine where this is supposed to happen based on pin numbers --- is this fix performed at the rear of the head unit, or at the BCM in the trunk? I'm trying to visualize where I'm supposed to splice in these components.carStereo wrote: ↑Fri Jan 24, 2020 7:10 pmreferring to the same post: http://www.mynissanleaf.com/viewtopic.php?f=36&t=26210
The build microphone can be used for OEM stereos with a little adapter.
... and to clarify, I've stared at the wiring diagrams (I have a 2013) and it would appear that the mic terminal pins are not the 37/38/39 (which are indicated to be in the harness) that "carstereo" posted... the service manual states Connector M84 [AUDIO UNIT] contains terminalncoig wrote: ↑Tue Sep 08, 2020 9:51 pmThis is a brilliant solution, but I'm not brilliant enough to divine where this is supposed to happen based on pin numbers --- is this fix performed at the rear of the head unit, or at the BCM in the trunk?

Thanks so much for replying!carStereo wrote: ↑Thu Sep 10, 2020 2:12 pmI used the mic adapter in a 2016 Leaf. Everything was easily accessible directly behind the head unit. The pins refer to the big connector going directly into the head unit. I never had to do anything in the trunk - thankfully
chumpp describes at https://www.mynissanleaf.com/viewtopic.php?f=36&t=23887 in all detail how to handle the 2013 -2015 Leaf, where the BT component is in the trunk - unfortunately. He suggests to "CHECK MY PIN NUMBERS FROM THE SERVICE MANUALS (2014 LEAF & 2015 SENTRA - select "AV" ". Nicoclub has those manuals. In essence you need to bypass the BT component in the trunk and use the existing wires to get the mic signal to a new headunit (which already contains its own BT module). For the 2013-2015 models, It may be a lot easier to just use the mic provided by a new headunit instead of dealing with the trunk ...
OK, so I'm at a loss. I followed (I think) your schematic, but all I get is HISS from the mic with a little bit of garbled garbage in the background, so I assume I have a hot mic.
...answered my own question...sort of... so I took the contraption out of the line and hooked the mic straight to the radio. Still garbled. Then I switched the pins. Worked like a charm with no caps or resistors.ncoig wrote: ↑Thu Oct 01, 2020 8:42 amOK, so I'm at a loss.

Just to be clear, the capacitor goes positive leg first from the mic, then to the 100kohm resistor on to the TIP of the plug, then bridging the 2.7kohm after the 100kohm across to the RING terminal?
The third wire is just to feed the 5V, which I'm doing from the trunk, so I should only have two wires hooked up behind the radio, yes?
I think I'm puzzling over the "Shield" terminology, which I am to understand is a ground from the mic, which is not grounded on its own at the mounting point.
