1. A method of conducting a route simulation operation on a screen of a navigation system, comprising the following steps of:

  • calculating a route from a starting point to a destination specified by a user;

    determining a first route simulation speed for a first part of the calculated route having a preset number of first turns from the starting point, the first route simulation speed being slow enough for the user to familiarize with the preset number of first turns;

    determining a second route simulation speed for a second part of the calculated route having a preset number of last turns before the destination, the second route simulation speed being slow enough for the user to familiarize with the preset number of last turns;

    determining a third route simulation speed for a part that extends between said first part and said second part of the calculated route, the third route simulation speed being higher than the first or second route simulation speed; 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.
