PROBLEM TO BE SOLVED: To provide a navigation device for vehicle capable of displaying the position of a vehicle with high accuracy. SOLUTION: Under normal conditions, a control part 11 calculates the reference position of the vehicle based on the results of outputs from a GPS receiver 13, a gyro-sensor 14, and a vehicle speed sensor 15, and displays it on a map on a display 17. When an ETC(Electronic Toll Collection System) receiving part 20 receives an ETC signal from an ETC transmitting part 21 the control part 11 corrects the reference position of the vehicle by using the ETC signal and displays the corrected position of the vehicle on the map on the display 17. |
