Head Unit Pinout Diagrams

Leo

Here is a detailed pinout diagram for the head unit.

It can be very useful when connecting external amplifiers, speakers, or other accessories.

Hope this helps others during installation or troubleshooting!

Well this helps, I won’t need to break out the multi-meter. The pins in connector B all say NC however. Does that stand for “Not Connected” to anything or just undocumented?

Hi Kaijinmaru,

Great question!

Connector B is generally reserved for the 360° surround view camera system. However, unless the head unit has been specifically customized or requested with the 360 module, the mainboard does not include the necessary chip for it.

So yes — the “NC” on those pins stands for “Not Connected”, meaning they are physically unconnected and non-functional in standard units.

Hope that clears it up! Let me know if you have more questions.

Best,
Leo
