摘要： A car-mounted equipment in which an ETC car-mounted unit and a navigation system work integrally together to share the data, making it possible to diversify the functions, to enhance the precision and to improve the reliability. The car-mounted equipment has an ETC car-mounted unit 11 which executes transmission and reception to and from an ETC on-the-road equipment to at least recognize that the vehicle is approaching or passing through a toll gate, a navigation system 12 which receives electromagnetic waves from a satellite to recognize the absolute position of the vehicle and informs the driver of at least the position of the vehicle by displaying data or by producing voice data, and a data bus 14 which connects the ETC car-mounted unit and the navigation system together so that they work integrally together, wherein the ETC car-mounted unit and the navigation system transmit and receive data to and from each other through the data bus.
