Abstract
Disclosed is a method for off-line routing by using a navigation terminal. The method includes the steps of creating second route guidance information in response to a route guidance request from a first location to a second location by utilizing first route guidance information, which had been stored in a navigation terminal for determining a route from the second location to the first location and outputting the second route guidance information as audio data, video data, or a combination thereof. Thus, a driver is not required to pay charges for route guidance information when the driver returns to the first location from the second location.
