Abstract:
A data device for a motor vehicle, comprising a database in which place data sets are stored in memory; a satellite receiver for receiving satellite signals suitable for determining position; means for selecting one place data set on a basis of a current vehicle position; means for determining a travel direction on a basis of a sequence of successive vehicle positions; and means for selecting only one or more such data sets whose coordinates are located along an ascertained travel direction, said means for selection of said data set being formed so that a selection of the one of two data sets that in the travel direction are located closest to the current vehicle position in front of and behind the vehicle is performed, and the selection being made on a basis of a comparison of a distance between the current location of the vehicle and coordinates of a preceding data set and a distance between the current vehicle location and coordinates of the next data set; means for ascertaining a distance between a current position and a position of the selected data set; and means for showing the distance or a time indication taking an average speed of the motor vehicle and the distance into account.
