A navigation instrument for use with a roadway vehicle to calculate and display the average speed of the vehicle and the deviations of the travelling distance and time of the vehicle from scheduled ones in accordance with the travelling distance and time and a scheduled vehicle average speed. The calculated results are not displayed and instead a zero-flashing or blanking indication is made to prevent the driver from having any unreliable information during the initial running operation of the vehicle.
