摘要:
There is provided an in-vehicle mount type navigation device in which a user can freely set a desired destination or via-places through which a route extending to the destination passes. A memory is provided with a destination/via-place table for storing data representing the destination and the via-places through which the route extending to the destination passes. A destination/registration place setting unit in a microprocessor stores data representing a place to be added in association with any specified one of a position between a via-place and another via-place or destination, and a position next to the destination into the destination/via-place table. On the basis of the data stored in the destination/via-place table, the guide route calculator of the microprocessor calculates a guide route which successively passes through the via-places and extends to the destination.
