PROBLEM TO BE SOLVED: To realize a navigation apparatus which is the combination of a navigation apparatus main body and an antenna part, and accordingly compact and easy to install. SOLUTION: The navigation apparatus includes an antenna 2, a map memory 4 for storing map data and a substrate 1a loading a processing part for realizing an original function of the navigation apparatus. The antenna 2 is incorporated at the uppermost part of the substrate 1a to open wide a view field to satellites. The map memory 4 is detachable to the substrate 1a. While the map memory 4 is attached to the substrate 1a, the map memory is a thin card memory 4 accommodated under the antenna 2 nor to hinder a directivity of the antenna 2. |
