The input from the user using the pop-up window 414 is received, and the facility ID of the facility corresponding to the selected facility icon and the received command are input to the preset point selection process.
[0058]
Next, when the operation of the “Make Destination” button in the candidate list window is accepted from the user or the “Make Destination” command 636 is input from the reception agent on the map (step 542), at that time The coordinates indicated by the connected road information registered in the facility data record of the selected facility are set in the destination data 303 of the parameter memory 106 (step 560). However, when the “Destination” command is input from the reception agent on the map, the facility data of the selected facility is selected as the facility of the facility ID notified from the reception agent on the map. The coordinates indicated by the connected road information registered in the record are set in the destination data 303 of the parameter memory 106. If the reception agent on the map is activated at that time, it is terminated (step 548), the destination candidate data 305 in the parameter memory 106 is cleared (step 550), and the process is terminated.
Next, in the case where the operation of the “Place to stop” button 637 on the candidate list window has been received from the user or the “Place to stop” command has been input from the reception agent on the map (step 544). The coordinates indicated by the connected road information registered in the facility data record of the facility selected at that time are added to the stop-by location data 302 of the parameter memory 106 (step 546). However, when a “drop-in place” command is input from the reception agent on the map, the facility data of the selected facility is selected as the facility of the facility ID notified from the reception agent on the map. The coordinates indicated by the connected road information registered in the record are added to the stop-by location data 302 of the parameter memory 106. If the reception agent on the map is activated at that time, it is terminated (step 548), the destination candidate data 305 in the parameter memory 106 is cleared (step 550), and the process is terminated.
[0059]
When the preset point selection process is completed as described above, the main control unit 107 displays the window used by the preset point selection process, the selected facility position display map displayed by the preset point selection process, and all destination candidates. The display of the position map is deleted, and the display of the display device 6 is returned to the display of the original navigation image. Further, as described above, a process for causing the route search unit 104 to search for a guidance route based on the destination data 303 and the stopover data 302 set in the preset point selection process is performed.
