We have this system in our Sienna and it is excruciatingly frustrating to try and use while you are on the road. You cannot enter in an address unless you come to a complete stop and put the vehicle in park. Despite the system being able to detect a passenger, for use with the airbag system. We will never again purchase the navigation/entertainment system from Toyota, if this "safety feature" is not changed. In fact, I seriously doubt I would purchase a Toyota again.
