PURPOSE:To make it possible to simply correct the data at a start point once inputted prior to starting running, by canceling the data at the start point and correcting a selectively changed-over desired point as the data of a new start point. CONSTITUTION:An operation key 2c is set as a lead one and the data at the start point of a vehicle and that of the objective point of a running destination are inputted by a code number of plural figures. The data at the start point is selectively changed over to a desired point by operation keys 2e-2i of an English character and canceled by a microcomputer 5 while the selectively changed-over desired point is corrected as the data at a new start point and running route guide data is operated on the basis of the data at the new start point and the data of the objective point. By this method, the data at the start point once inputted by a code number can be simply corrected to the data at the desired point only by operating one selection switch. |
