Step 1 — Remove the Factory Head Unit
-
Use a plastic trim tool to safely pry open the dashboard bezel.
-
Unscrew the mounting bolts and carefully slide out the factory head unit.
-
Disconnect all the factory plugs and keep them accessible for wiring.
Step 2 — Connect to the Factory Harness
For Type 3, the harness configuration is slightly different but follows the same logic:
-
Main Power Harness → supplies power and connects to factory wires.
-
AC/Climate Control Cable → retains the A/C display and climate buttons.
-
CAN/Protocol Plug → essential for steering wheel buttons and data.
-
AUX Cable → sends audio to the Bose amplifier.
-
Reverse Trigger Wire → connects to reverse light for camera signal.
-
Illumination/Key Wire → required for dash lighting sync (if applicable).
👉 Ensure every connector is locked in place and matches the diagram.
Step 3 — Plug All Cables into the Android Head Unit
Connect all ports before switching on:
-
Main Power Harness
-
GPS Antenna (mount near windshield or A-pillar)
-
4G/LTE Antenna (if supported by your unit)
-
Wi-Fi Antenna (external if included)

-

⚡ Important: Always power on and test all functions before reassembling the dashboard.
