Step 1 — Remove the Factory Head Unit
-
Use a plastic trim tool to carefully open the center console bezel.
-
Unscrew the factory head unit and gently pull it out.
-
Disconnect all the original plugs.
Step 2 — Connect to the Factory Harness
Match the harnesses as shown in the wiring diagram:
-
Main Power Harness → connects to the factory power and speaker wires.
-
AC/Climate Panel Cable → keeps the air conditioning display and controls functional.
-
CAN/Protocol Plug → required for steering wheel controls and vehicle data.
-
AUX Cable → routes sound to the factory Bose amplifier.
👉 Make sure every plug clicks in place securely.
