1. A navigation apparatus for providing a driver with different types of information, comprising:
- means for allocating a priority order, indicative of priority for information provision in accordance with a type of inputted information and a travel classification indicative of at least one of running state, driving purpose and running environment, to inputted information;
means for changing a value of the travel classification in accordance with a change in at least one of the running state, driving purpose and running environment in a case where the at least one of the running state, driving purpose and running environment changes;
means for selecting a first type of inputted information having a higher priority order than a second type of inputted information in a case where types of the first and second types are different from each other;
means for providing the driver with the selected first type of inputted information; and
determining means for determining, after the selected first type of inputted information is provided, whether or not the unselected type of second type of inputted information is to be provided in accordance with a travel classification of the unselected second type of inputted information.

19. A navigation apparatus for providing different types of information, comprising:
-
means for allocating, to inputted information, a rank indicating a type of the inputted information, and a priority order indicating a priority degree of the inputted information;
means for determining a lower limit value for ranks in accordance with at least one of running state, driving purpose and running environment;
means for changing a value of the lower limit in accordance with a change in at least one of the running state, driving purpose and running environment in a case where at least one of the running state, driving purpose and running environment changes; and
means for selecting one or more information allocated with a rank value higher than a lower limit value determined by said determination means, and successively providing the selected one or more information in accordance with values of priority order allocated to said one or more information. - View Dependent Claims (20, 21, 22)

23. A navigation apparatus for sequentially providing different types of information inputted successively, comprising:
-
means for allocating a rank to inputted information in accordance with a type of the inputted information;
means for setting an urgency level indicating a degree of urgency of the inputted information with respect to travelling, the urgency level being set to either one of a highest first, intermediate second and lowest third values in consideration of the allocated rank and at least one of running state, driving purpose and running environment; and
control means for allowing a provision of the inputted information suspending the provision of the inputted information until the provision is allowed, and canceling the provision of the inputted information when the set urgency level indicates the highest first, intermediate second and lowest third values, respectively. - View Dependent Claims (24, 25)

30. A navigation apparatus for providing a driver with different types of information, comprising:
-
means for allocating a priority order to inputted information in accordance with a type of the inputted information, the priority order being prescribed in accordance with a quality of information;
means for selecting a type of information having a high priority order in a case where there are a plurality of types of information to be provided; and
means for providing the driver with the selected information in accordance with a priority order of the selected type of information, wherein in a case where information, having the same information as information of the already inputted information, is inputted, the priority order of the inputted information is set low.
