PROBLEM TO BE SOLVED: To provide a navigation apparatus for informing the shining of direct sunlight into a driver's seat of a driver in advance. SOLUTION: Based on information for indicating the altitude and azimuth of the sun corresponding to current date/time and information for indicating change in the advance direction of an own car that are stored at a sun locus storage section 18, it is judged whether the direct sunlight shines into the driver' s seat or not, and from which direction the direct sunlight shines in. Further, the navigation apparatus 100 reads voice information in response to the judgment result from a non-illustrated memory at an information-processing section 30, and converts the read voice information to an analog voice signal via a voice information-outputting section 44 before outputting to a speaker 46. |
