Step 1 — Remove the Factory Head Unit
-
Use a plastic trim tool to carefully open the dash bezel.
-
Unscrew the factory screws and slide out the head unit.
-
Disconnect all plugs from the factory harness.
Step 2 — Connect to the Factory Harness
Type 2 uses a slightly different harness layout. Match each connector according to the diagram:
-
Main Power Harness → connects to the car’s power and speaker wires.
-
AC/Climate Control Cable → keeps A/C display and control buttons working.
-
CAN/Protocol Plug → required for steering wheel controls and data communication.
-
AUX Cable → routes sound into the Bose amplifier.
-
Reverse Trigger Wire → connects to the car’s reverse light for backup camera activation.
👉 Double-check all plugs click firmly into place.
Step 3 — Plug All Cables into the Android Head Unit
Connect every required port before powering on:
-
Main Power Harness
-
GPS Antenna (place near windshield/A-pillar)
-
4G/LTE Antenna (if supported)
-
Wi-Fi Antenna (if external)

-
RCA IN/OUT (front/rear camera, subwoofer, external amp)

⚡ Tip: Do not reassemble the dash until you confirm the system boots and all functions work.
