摘要

PROBLEM TO BE SOLVED: To provide a navigation technique capable of avoiding inconvenience on the payment of tolls by notifying a user of that the upper limit sum of use of the ETC previously set by the user is exceeded in the case that he uses a toll road. SOLUTION: A present location computing part 40, a destination specifying part 41, a route computing part 42, a guidance 43, an upper limit sum storage 44 for storing the upper limit sum of use of the ETC, a use sum integrating part 45 for integrating the sum of use, a cumulative use sum storage 46 for storing the cumulative sum of use, an adder 47 for adding the toll of use of the toll road to the cumulative sum of use before the use of the toll road of the motor vehicle, a toll comparator 48 for comparing the added sum with the upper limit sum of use, and an alarm annunciator 50 for outputting an alarm in the case that the added sum exceeds the upper limit sum of use, are set in the main CPU of this navigation device for a motor vehicle provided with an ETC on-board machine 15 and its peripheral circuit 4.
