PROBLEM TO BE SOLVED: To easily perform destination setting and response.SOLUTION: A position detection part 41 receives a positioning signal to detect a current position. A map data storage part 45 stores map data. A short-distance communication part 46 performs communication with a communication terminal device. A navigation control part 47 sets a destination by using positional information contained in received information received by the short-distance communication part 46, calculates an estimated time of arrival at the set destination on the basis of the map data and the current position, and transmits response information indicating this calculated estimated time of arrival through the short-distance communication part from the communication terminal device. The destination can be easily set to the position indicated by the positional information. Moreover, response of the estimated time of arrival is easily performed. |
