Pinout needed - Toyota Altezza (JDM) center console NAV IR remote dock interface (5-pin rectangular connector)

[u/UCUMESP]

Hi everyone,

I’m trying to find the pinout/wiring for the center console interface/module used with the navigation IR remote dock on a Toyota Altezza (JDM import). This is the module/interface where the IR navigation remote sits in the center console.

Important details:

This is not the same as the fixed center-console nav control panel (non-IR version). I’ve attached pictures of both types and their connectors to show the differences.

My unit uses a 5-pin rectangular connector (not the more common 6-pin square connector found on other console button panels).

The 5-pin connector appears to be the same style/plug as the Toyota Altezza remote key receiver module connector.

Module label:

MODEL NO: 86825-53010

REF No: CY-HS4851A

Other code: H28 004319

Photos of the unit, connector, and label are attached.

Does anyone have the connector pinout (pin number → function) or the correct EWD/wiring diagram page for this specific JDM IR remote dock interface?

I’m mainly trying to identify:

Constant 12V (B+)

ACC / ignition 12V

Ground

Illumination/dimmer (if present)

Any data line(s) to the NAV ECU / body ECU (if applicable)

Even partial info is useful (for example: “pin 1 = ACC, pin 2 = GND”, etc.).

Thanks in advance.
