Canbus protocol setting tutorial
Some special models require the original car decoder to support certain functions of the original car, such as multi-function steering wheel buttons, door opening and closing information, original car mileage information, original car reversing rear view, original car lights, power amplifier settings, etc. Requires a protocol box for support.

The factory default is that the model is not set, so you need to set it according to your vehicle model.
