2006 Camry Stereo Replacement — help

I’m trying to replace my car stereo in my 2006 Toyota Camry XLE with navigation system. I had the default navigation system Denso DW468100-0150 and wanted CarPlay and Bluetooth, so I bought the Pioneer AVH4200NEX 2-DIN Receiver

I followed the Cruchfield and Amazon “it fits” guides for my vehicle, but the Metra 70-1761 Radio Wiring Harness For Toyota 87-Up Power 4 Speaker doesn’t fit into my 20 pin connector shown below. Additionally, I can’t figure out my pin colors or how to connect things.

Update: I think I need the Metra-70-8113

This post gets close and explains a lot, but the colors don’t match.


My existing connectors

20 pin CN703 — probably (Power, Audio Outputs)

12 pin CN702 (no idea what it does)

5 pin ( also, no idea what it does)

Potentially Useful Resources
