    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: 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.
