  According to the first embodiment, as in step S40 in FIG. 5 and step S56 in FIG. 6, the first communication unit 60 of the mobile device 10 transmits information to the second communication unit 80 of the in-vehicle navigation device 30. Then, the first image control unit 68 deletes the character 2 image from the first display unit 24, and the second image control unit 88 causes the second display unit 44 to display the character 2 image. For this reason, it becomes easy to understand that the vehicle-mounted navigation device 30 is operating.

  Similarly, in response to the second communication unit 80 of the in-vehicle navigation device 30 transmitting information to the first communication unit 60 of the portable device 10 as in step S46 of FIG. 5 and step S78 of FIG. The image control unit 88 deletes the character 2 image from the second display unit 44, and the first image control unit 68 causes the first display unit 24 to display the character 2 image. For this reason, it becomes easy to understand that the portable device 10 is operating.

  That is, according to the first embodiment, one of the first communication unit 60 and the second communication unit 80 transmits information to the other of the first communication unit 60 and the second communication unit 80. One of the corresponding ones of the first image control unit 68 and the second image control unit 88 erases the image of the character 2 from the corresponding one of the first display unit 24 and the second display unit 44, and the first image The other of the control unit 68 and the second image control unit 88 displays the character 2 image on the other of the first display unit 24 and the second display unit 44. For this reason, by visually recognizing the image of the character 2, it is possible to easily understand which of the mobile device 10 and the in-vehicle navigation device 30 is operating.

  The image displayed by any one of the first image control unit 68 and the second image control unit on the corresponding one of the first display unit 24 and the second display unit 44 is not the image of the character 2 but the portable device 10. Any image can be used as long as it can recognize which of the navigation device 30 and the in-vehicle navigation device 30 is operating. However, displaying the character 2 image makes it easier for the user to recognize the image than when only the character is displayed, for example. That is, it becomes easier to understand which of the mobile device 10 and the in-vehicle navigation device 30 is operating. For the character 2, for example, animals, plants, mascots and the like can be used.

  By transmitting and receiving destination information and parking position information between the portable device 10 and the in-vehicle navigation device 30, the in-vehicle navigation device 30 guides the vehicle to the vicinity of the destination while getting on, and after getting off, the portable device 10 The user can be guided to the destination. In addition, on the return trip from the destination, the mobile device 10 can guide the user to the parking position. Moreover, the information transmitted / received between the portable apparatus 10 and the vehicle-mounted navigation apparatus 30 may be information other than the destination information and the parking position information.

  A display for identifying transmitted information, such as a G mark indicating destination information and a P mark indicating parking position information (see FIGS. 9A to 10C), may not be displayed. However, displaying the G mark and the P mark together with the image of the character 2 makes it easy to understand what information is transmitted.

  The notification by the notification unit 26 may not be performed (Step S42 and Step S48 in FIG. 5). However, when the notification unit 26 generates sound, vibration, or sound and vibration, the user can recognize that information has been transmitted through not only vision but also hearing and touch. For this reason, it is preferable that notification by the notification part 26 is performed.

  In Example 1, after the second guide unit 86 of the in-vehicle navigation device 30 searches for a route, the second image control unit 88 deletes the character 2 image from the second display unit 44 (step S62 in FIG. 7). It is assumed that the image of character 2 is displayed after reaching the ground (step S72 in FIG. 8). In other words, the image of character 2 is not displayed during route guidance. However, route guidance may be performed while the image of the character 2 is displayed.

  As a modification of the first embodiment, an example using a plurality of portable devices will be described. FIG. 11 is a schematic diagram illustrating a navigation device according to a modification of the first embodiment. The configuration of each portable device is the same as that shown in FIGS.

  The CP 50 stores images (a plurality of third images) of a plurality of different characters (referred to as a first character and a second character), and the user can select an arbitrary image from the plurality of images. it can. As shown in FIG. 11, the first image control unit 68 of each of the first portable device 10a and the second portable device 10b receives each of the first character image and the second character image from the CP 50 via the telephone IF 28. to download. The first communication unit 60 of each of the first portable device 10 a and the second portable device 10 b transmits the first character image and the second character image to the in-vehicle device 30.
