Looking for info on the wires at the radio unit from my 2012 GXL.
I’ve fitted an aftermarket head unit but it has an external microphone.
I’d prefer to use the standard unit mounted in the overhead map light console.
I figure the microphone wires must go from that overhead unit to the 20 pin plug on the back of the old radio, but which wires?
The new head unit uses a patch cable to only a few of the 20-pin plug wires.
If I can grab the factory mike wires at that plug, I can make a patch cable to connect to my new head unit’s mike in port.
