The system is compatible with the car's electrical system and safety system. Automatic folding/unfolding, effective anti-scratch and anti-collision. It can be equipped with the existing electronic system and other safety devices on the car. Once the ignition is on, the car's rearview mirrors and taillights will automatically expand. When the ACC is closed, the mirrors will automatically fold. When the ACC is off, the rearview mirror is automatically retracted when the central control lock is unlocked. When the ACC is on, the rearview mirrors on both sides are automatically extended, and only the original car's rearview mirror switch can be controlled. In the closed state of ACC, the rearview mirror is automatically extended when the central control lock is unlocked. Overload protection, if the door is closed/opened too frequently, the system will stop folding/unfolding the side mirror to protect the side mirror motor. Easy installation, no need to modify the original car lines and
