In a car navigation system (), a position information detection means () detects position information on a vehicle using, for example, a GPS. A travel information history of the vehicle obtained based on the detected position information is accumulated in a travel information history means (). When detecting an event such as start of an engine, an action prediction means () predicts a destination of the vehicle by referring to a route to the current time and to the accumulated travel information history. Commercial or traffic information regarding the predicted destination is acquired by an information acquisition means () from a server (), and then is displayed on a screen, for example, by an information provision means ().
