This is an absolute must have modification if you have kids or ever have anyone in the back seat who uses electronic devices. The switch plate eliminates the seldom used rear seat audio controls (must have rear seat audio controls to use this) with functional USB ports allowing everyone in the back to charge devices without having to run long cords from the front seat console. These charging port plates are 3D printed from durable and heat resistant ABS for long life. Uses standard Toyota 33mm x 22.4mm size charging ports. Charging ports NOT included.
