NAVIGATION DEVICE
The present invention relates to an improved vehicle navigation device that is capable of simulating the journey of a vehicle on an alternative travelling route in real time and based on real traffic data, together with indicating the guidance of the vehicle along a selected actual route. The vehicle navigation device is thus capable of indicating, on a common display screen, both the actual position of the vehicle on the actually driven route, and a simulated position where the vehicle would have been located at the same instance of time if the alternative route had been chosen for driving thereon.
