    摘要: An on-board navigation apparatus having a GPS receiver detects a difference between the current and the previous values of the estimated current position in terms of the longitude and latitude information gained from GPS data. The difference is added to the coordinates of the previously established position, the result being taken for the coordinates of the estimated current position. This makes it possible to estimate the current position coordinates accurately even if the accuracy of GPS data is not high enough. When the GPS receiver is in a two-dimensional measuring state, the coordinates of the estimated current position are obtained from a manually or automatically designated elevation value and from the GPS data. This allows the current position coordinates to be estimated with accuracy even if the accuracy of GPS data has dropped due to the two-dimensional measuring instead of a three-dimensional measuring.

    摘要: An onboard navigation system detects a condition that a recognized present position of the vehicle belongs to a map of a peripheral part of a region covered by map data groups recorded on a recording disc. If a changer type driver is used as a player for reproducing map data, the recording disc being played is changed to a new disc in response to the detection of the above described condition. If a single driver is used, identification information of a corresponding disc is displayed. With these features, the disc being played is quickly changed to a required new disc.

    摘要: In an information reproducing apparatus, when a car is travelling, it is inhibited that the image information played back by a DVD reproducing apparatus is displayed on a display device, or the map information outputted from a navigation system is displayed. Further, when the control information for the play back control is recorded in an information medium played back by the DVD reproducing apparatus, even when the car is travelling, the operation state of the DVD reproducing apparatus according to the control information is displayed on the display device by the superimposition display.

    摘要: A navigation system includes a device for extracting map data and location name data of different locations and their corresponding coordinate data; a position detector which detects the vechile position; a map display controller which displays map data on a display, and a calculating device for determining a straight-line distance from the vehicle position to the different locations thereby producing distance values. A location name display device displays location names on the display in ascending order based on the distance values, and a user selects a desired location from among the location names displayed. The extracting device may segregate the different locations based on different categories, and the map display controller retrieves map data around a location represented by coordinate data corresponding to the desired location selected by the user.
