In a navigation apparatus having a base unit (10) that is fastenable to a dashboard (D) at a driver's seat of a vehicle; a front panel unit (14) that is attachable to and detachable from the base unit and is equipped with a display (14b) displaying map data; and a microcomputer that performs a navigation function to indicate a determined location of the vehicle on the map data, it is configured such that a part of the front panel unit (14) projects from a surface (Dw) of the dashboard (D) toward a user seated in the driver's seat, as viewed from side, when the front panel unit (14) is attached to the base unit (10). With this, the degree of freedom of front panel unit attachment/detachment with respect to the base unit is improved without sacrificing the appearance of the navigation apparatus.
