A method for route simulation operation on a navigation system is able to complete the route simulation operation within a short period of time. The method includes the steps of: calculating a route from a starting point to a destination; determining a first route simulation speed for a preset number of first turns from the starting point; determining a second route simulation speed for a preset number of last turns before the destination; determining a third route simulation speed for a remaining part of the calculated route; and displaying a progression indicator on the calculated route to the destination on a map image on the screen of the navigation system and moving the progression indicator based on the simulation speeds determined in the above steps.
