A method of controlling a vehicle navigation apparatus included in a vehicle, and which includes displaying road guidance information on a touch screen display of the vehicle navigation apparatus and including a set travel route from a current position of a vehicle to a destination, determining, via a controller, whether a particular road displayed on the road guidance information has been drawn on, said particular road corresponding to a road that is different than a road included in the set travel route from the current position of the vehicle to the destination, and setting, via the controller, a road matched to the particular road that has been drawn on as a detour. |

1. A method of controlling a vehicle navigation apparatus included in a vehicle, the method comprising:
displaying, via a controller, a map on a touch screen display of the vehicle navigation apparatus; displaying, via the controller, road guidance information on the map and including a set travel route from a current position of a vehicle to a destination; receiving, via the controller, a user input corresponding to a request for magnifying or reducing the map for setting a detour road; magnifying or reducing, via the controller, the map based on the user input; receiving, via the controller, an input corresponding to a request for beginning a detour operation; fixing, via the controller, the magnified or reduced map displayed on the touch screen display upon receiving the input corresponding to the received request for beginning the detour operation; determining via the controller, whether a line has been drawn on the fixed map, said line being different than a road included in the set travel route from the current position of the vehicle to the destination; determining, via the controller, a current speed of the vehicle; finding, via the controller, a plurality of roads that match the drawn line; automatically setting, via the controller, a road closest to a pre-set travel road as the detour road among the plurality of found roads; determining, via the controller, a vehicle speed limit for setting the detour road; comparing, via the controller, the vehicle speed limit with the determined current speed of the vehicle; and distinctively displaying, via the controller, the set road as the detour road only when the comparing step determines the current speed of the vehicle is less than the vehicle speed limit.
