Do you think the in-vehicle system will be replaced by mobile navigation in the future?

I don't think it will be replaced by mobile navigation, because the on-board system is a function of the car itself, and it will be more convenient to use than mobile navigation. Moreover, once some people's habits are formed, they are not easy to change. If he had used the in-vehicle system from the beginning, he wouldn't have given up this to use mobile navigation.
