Patent attributes
In a main device, a processor receives information about a destination point, and further generates guide image data representing a guide image for guiding a user who is driving a vehicle. A display unit displays the guide image generated by the processor, thereby guiding the driving user to the destination point. When it is determined, while guiding the driving user, that the user is going to get off the vehicle, the processor generates navigation data Dnvg including the information about the destination point, and transfers the navigation data to a sub-device. In the sub-device, a processor generates, based on the received navigation data Dnvg, guide image data for outside of the vehicle representing a guide image for guiding the user who is traveling to the destination point on foot. A display unit displays the guide image generated by the processor. Thus, it is possible to provide a navigation system that is convenient to use.
