Problems solved by technology

[0008] However, when data for output is transferred from the navigation device to the information input / output device, the amount of data per unit time cannot be increased.
Therefore, for example, when the driver wants to change the output status by scrolling the map screen through the operation of the operation unit, the map screen will be blank for a while, and the data processing for output cannot be performed smoothly.

Abstract

The invention provides a navigation device which has an information acquisition processing device used to acquire map data, an output data generation processing device used to generate output data at least used in map display according to the map data as well as an output data transmission processing device used to transmit the output data more than the data quantity of one output subarea to an information input / output device in order to transfer an output subarea. Because the output subarea is transferred so as to transmit the output data more than the data quantity of one output subarea to the information input / output device, smooth processing of the output data can be realized when output state is to be changed.

Description

technical field [0001] The present invention relates to a navigation device, an information input / output device, a navigation system, a program of a navigation method, and a program of an information input / output method. Background technique [0002] Conventionally, in a navigation device, for example, a GPS (Global Positioning System) is used to detect the current position of the vehicle, that is, to detect the current location, and at the same time, the orientation of the vehicle is detected based on the rotation angle of the vehicle detected by a gyro sensor, that is, the For the direction of the car, the map data is read from the data recording unit, a map screen is formed on the display unit, and a map showing the position of the car and its surroundings is displayed on the map screen. Therefore, the driver as the operator can drive the vehicle based on the position of the vehicle and the map displayed on the map screen. [0003] Furthermore, when the driver inputs a d...
