Yes, I've heard , but I am novice, and not a "car guy". I feel uncomfortable trusting my and family's life to an aftermarket accessory at highway speeds. Is the electronics/circuit board for cruise already in every Yaris by default? Then why wont Indus offer it themselves?
Also, wont it void the warranty/electrical warranty in Toyota Indus' eyes? I fully expect them to deny warranty in case of any fault in car.
