I'm trying to replace my OEM headunit for my 2012 GTS with a Sony XAV-AX5000.
I've purchased some wire-harnesses and gear from as per the instructions here:
https://aerpro.com/vehicles/toyota/toyota-86-2012-2015
The stock head unit is a PZQ60. Here is a wiring diagram (Please not, this image does not necessarily correspond to mine 100%, but it appears to be as close as I could find)
I had to solder:
- The wire from the Sony harness reverse wire to the corresponding wire from the stock 28 pin.
- The wire from the Sony harness parking brake wire to the CN4800 parking brake connector wire.
- The blue wire from the Sony harness to my antenna adapter.
Headunit starts up, but immediately I noticed the Sound quality had been lowered. I tried mucking around with the Equalizer settings, but still felt something was off. At first I thought maybe it was a placebo. In particular the Radio felt a bit weak. While searching, I found out someone else had an issue regarding the Sony unit, particularly the Blue/White wire. See here:

So I took the headunit back out and started tracing the blue wire which appears to be the AMP turn on. So the soldered Antenna adapter and Sony harness blue wire both connect back to the OEM CN1 Pin. But, to my surprise it connected to nothing!

I had a look around, someone in another post said pin 9 on the 28 connector (CN6) could be rerouted, but I did not find anything there. Here is my 28 pin, the darker spots indicate where there is a wire connecting:
The 28 pin connector appears to split out into another one, perhaps something I could hijack there? I could not find a corresponding wire at pin 9 either.
Kind Regards
