A vehicular display device, in which positional adjustment of a display image is easy, is provided, and the vehicular display device (head-up display)comprises a displayto emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means (motor)for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means (control unit)to allow driving of the moving meansand control meansfor displaying a mark indicative of a display range of the display image when the operation meansis operated.

Vehicle display device

There are included a sensor which outputs pulse signals corresponding to the traveling distances of a vehicle, a vehicle display device which displays, based on the pulse signals, vehicle information including the traveling distance, and a navigation unit which receives the distance data related to the traveling distances, obtained by processing the pulse signals, being outputted from the vehicle display device or the pulse signals at a certain reception period to calculate the present position of the vehicle, and controls the vehicle display device to display road traffic information including the display synthesized with the present position on a map in accordance with map data read from a map information memory medium . If the navigation unit can not receive the distance data or the pulse signals within the reception period, an estimated value of a value to be received this time is obtained from the difference between a value inputted last time and a value inputted last time but one and the navigation unit calculates the present position in accordance with the estimated value.
