PROBLEM TO BE SOLVED: To efficiently deal with a voice data without increasing a communication load, even when a storage capacity is limited, in a navigation system using a terminal device such as a cellular phone. SOLUTION: In this navigation system 10 including a route search server 30 for distributing a start point and a guide route up to a destination, to the terminal device 20, the route search server 30 is provided with a voice database 318 for accumulating the voice data distributed to the terminal device 20, while correlated with an identification code in every unit voice data, by dividing the voice data into the unit voice data, and distributes a distribution data to the terminal device 20 while adding the identification code to the distribution data, when the voice data is required to be added in the distribution of the data requested from the terminal device 20, and the terminal device 20 stores the distributed identification code, and requests the distribution of the corresponding unit voice data to the route search server 30, based on the identification code, when a voice output gets necessary.
