Smart Paddle, fixed on Steering wheel， gives  another way to operate  buttons on Steering wheel, same like "Blind operate", easy to turn on left turn/right turn indicator, or to flash On/Off high beam, trigger the wipers! 

Smart dock, stuck in Steering wheel,   expands new physical buttons to open the doors, fold/unfold mirrors, open glove box, move the seat,  even some hidden function like preheating battery.
