<P>PROBLEM TO BE SOLVED: To provide a navigation system, a terminal device, a navigation server, a navigation device, a navigation method and a program that, when an unmeasurable place exists on a guidance route to a destination, can present information concerning the unmeasurable place. <P>SOLUTION: A navigation system searches a guidance route which meets route search conditions, using network data, generates route guidance information including at least guidance route data, acquires current position information of a user, executes route guidance by outputting the acquired current position information and the generated route guidance information via an output unit, and if acquisition of the current position information fails during the route guidance, generates positioning failure point information associating coordinate information of a positioning failure point with coordinate information of a destination to output the generated positioning failure point information via the output unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
