  • On-vehicle apparatus
    Patent number: 9116012
    Abstract: A storage part of an on-vehicle apparatus stores simplified map data of which content is simplified as compared to original map data used for route guidance. An image generator of the on-vehicle apparatus retrieves the simplified map data stored on the storage part and generates a map image based on the simplified map data. Then a transmitter of the on-vehicle apparatus transmits the map image generated by the image generator to a portable device, in response to a demand from the portable device.

  • In-vehicle apparatus
    Patent number: 8977330
    Abstract: An in-vehicle apparatus links up with a mobile device that executes an application. A memory of the in-vehicle apparatus stores acoustic data of a sound relevant to the application, and a receiver receives a direction signal transmitted from the mobile device at a timing specified by the application. An output part of the in-vehicle apparatus outputs the sound based on the acoustic data stored in the memory via a speaker in response to the direction signal received by the receiver.
