In step S3, when the sub-display 21 is activated and a CD or the like is being played back, information such as the song performance time and song name is displayed on the sub-display 21, and then the process proceeds to step S61. In step S61, it is determined whether or not it is route guidance timing such as an intersection. If it is not the route guidance timing, the process proceeds to step S64. If it is determined that it is the route guidance timing, route guidance information ( For example, a process of displaying a guide information such as “Please turn right at the intersection after XX m”) for a certain time (step S).
62). In addition, in order to notify the user of the display of the route guidance information in accordance with the display on the sub-display 21, a buzzer sound may be sounded or the route guidance information may be output by voice. Thereafter, it is determined whether or not the vehicle has passed the guidance point (step S63). If it is determined that the vehicle has passed the guidance point, the process proceeds to step S64. In step S64, it is determined whether or not the vehicle has deviated from the set route. If it is determined that the vehicle has deviated from the set route, detour information (for example, “depart from the set route XX
Information such as “heading in the direction” is displayed for a certain period of time. In order to notify the user of the display of the off-route information in accordance with the display on the sub-display 21, a buzzer sound may be sounded or the out-of-route information may be output as a sound.

On the other hand, if it is determined in step S64 that the vehicle does not deviate from the set route, the distance to the destination is obtained, and it is determined whether or not the predetermined distance has been reached (step S66).
If it is determined that the predetermined distance is not reached, the process proceeds to step S8. On the other hand, if it is determined that the predetermined distance is reached, the sub-display 21 displays distance information (for example, “remaining to the destination”). (The information such as “It is km”) is displayed (step S).
67) Thereafter, the process proceeds to step S8 and subsequent steps.

According to the information terminal device according to the above embodiment, even when the main display 20 is in the closed state, the information desired by the user, i.e., the sub display display setting, is not performed without performing the operation of bringing the main display 20 into the open state. Pre-set information (VI
CS information, ETC information, EPG information, current location information, peripheral facility / store information, or route guidance information) can be displayed on the sub-display 21. Therefore, a part of the information displayed on the main display 20 when the main display 20 is in the open state can be visually recognized by the user through the sub display 21 when the main display 20 is in the closed state. When mounted on a vehicle, the driver can prevent the main display 20 from being opened during driving, and the safety during driving can be prevented from being impaired.

If it is determined that the main display 20 is in the open state, the sub-display 2
Since the display of 1 is stopped, wasteful display power consumption can be eliminated. Further, user-desired information (VICS information, ETC information, EPG information, etc.) displayed on the sub-display 21 is stored in the HDD 19, so that if the display on the sub-display 21 is missed, it will be later received from the HDD 19. It can be read and displayed.
