Important Wiring Notes:
- If the car radio does not power on, ensure the Canbus is correctly connected to the 20-pin plug.
- The RCA interface is for RCA cables only. Do not insert the 20-pin plug into the RCA interface, as this will cause a short circuit. The 20-pin plug should connect to the Canbus box.
- If your car's original plug and interface match the provided photo, you may need an additional power harness. This can be purchased separately (e.g., B0F8QD946D).
- If your original car has a Bose system, a 4 or 8-inch central control screen, and the power cord interface matches the figure, a decoder box (asin: B0F9K58LXD) is required.
