Claim One:
1. A navigation system including a center apparatus and an in-vehicle navigation apparatus in a vehicle, the center apparatus being communicable with the in-vehicle navigation apparatus via a communication network, the center apparatus comprising: a center communication device configured to communicate with the in-vehicle navigation apparatus for receiving a present position and a destination from the in-vehicle navigation apparatus; a route calculation device configured to calculate a route from the present position to the destination by searching map data; and a center control device configured to extract a passing point in the route, calculate course information indicating a course at the passing point the vehicle is to take, and cause the center communication device to send the course information along with the passing point to the in-vehicle navigation apparatus, the in-vehicle navigation apparatus comprising: a present position designation unit configured to designate a present position; a destination designation unit configured to designate a destination; an in-vehicle communication device configured to communicate with the center apparatus for sending the present position and the destination and receiving the course information along with the passing point; a forward image capture unit configured to capture a forward image including the received passing point in a travel direction of the vehicle; and an in-vehicle control device configured to display (i) the captured forward image and (ii) the received course information, which is superimposed on the displayed forward image, when a present position designated by the present position designation unit approaches the received passing point, wherein in the center apparatus, when the route calculation device calculates multiple routes from the present position to the destination by searching the map data, the center control device extracts a passing point included in one of the multiple routes, the one of the multiple routes being selected in the in-vehicle navigation apparatus, calculates course information indicating a course at the extracted passing point included in the one of the multiple routes, and causes the center communication device to send the calculated course information along with the passing point included in the one of the multiple routes to the in-vehicle navigation apparatus.
