    摘要: A navigation unit having a gyro sensor mounted thereon. The unit includes a mounting mechanism for changing the mounting direction of the gyro sensor so that the rotation detecting axis of the gyro sensor may be vertical, i.e. normal to a vehicle. In one embodiment, the navigation unit includes a support device for supporting the gyro sensor rotatably with respect to a casing. The gyro sensor may be supported in a rocking manner in the casing, and mounted to be changed between a first mounting direction and a second mounting direction perpendicular to the first mounting direction. In the preferred construction, the gyro sensor has a first pin and a second pin, and the casing has a first guide groove for receiving and guiding the first pin, and a second guide groove extending perpendicular to the first guide groove for receiving and guiding the second pin. The second guide groove provides a rocking center for the gyro sensor.

    摘要: Navigation systems, display changeover methods and programs, and display devices display an image, detect a turn amount and a turn direction, and scroll the displayed image based on the detected turn amount and the detected turn direction. The navigation systems, display changeover methods and programs, and display devices determine whether the detected turn amount is at least a predetermined turn amount in one direction within a preset period and continuously scroll the displayed image in the detected turn direction when the detected turn amount is at least the predetermined turn amount in the one direction within the preset period.
