The in-vehicle information system according to claim 1, wherein, at a time of display output of the optional guidance information to the display unit, the information output unit stops outputting the optional guidance information and automatically returns to a normal information display screen and a normal display operation that outputs the various types of guidance information including both the optional guidance information and the optionally-eliminated guidance information to the display unit according to said predetermined timings, when no touch operation has been received by the input unit by users after a predetermined period of time. 3. The in-vehicle information system according to claim 1, wherein a plurality of the display input units to which touch operations can be performed are mounted on the vehicle, andthe information output unit automatically returns to the normal information display screen and the normal display operation that is synchronized with a normal information display switching timing of various types of information being displayed on other display input units that have not received a touch operation. 4. The in-vehicle information system according to claim 3, wherein, when an event requiring display of emergency guidance information to be transferred to the users occurs during an operation of synchronizing switching with the normal information display switching timing, the information output unit prioritizes switching to the emergency guidance information over waiting to synchronize display of the various types of information with the normal information display switching timing. 5. The in-vehicle information system according to claim 1, wherein a touch-operation available area visualized with a predetermined fixed phrase or a predetermined fixed graphic is clearly indicated in a part of a screen area of the display unit, andthe information output unit outputs the optional guidance information desired by a user to the display unit according to a touch operation to the touch-operation available area. 6. The in-vehicle information system according to claim 1, wherein a touch-operation available area visualized with a translucent predetermined fixed phrase or a translucent predetermined fixed graphic is clearly indicated in a part of a screen area of the display unit, andthe information output unit outputs the optional guidance information desired by a user to the display unit according to a touch operation to the touch-operation available area. 7. The in-vehicle information system according to claim 1, wherein a transparent touch-operation available area is provided in a part of a screen area of the display unit, andthe information output unit outputs the optional guidance information desired by a user to the display unit according to a touch operation to the touch-operation available area. 8. The in-vehicle information system according to claim 1, wherein a transparent touch-operation available area is provided in a part or all of a screen area of the display unit, andthe information output unit outputs the optional guidance information desired by a user to the display unit according to a direction of a touch operation. 9. The in-vehicle information system according to claim 1, wherein a transparent touch-operation available area is provided in a part or all of a screen area of the display unit, andthe information output unit outputs the optional guidance information desired by a user to the display unit according to a direction and an acceleration of a touch operation. 10. The in-vehicle information system according to claim 1, wherein a predetermined driving period of the vehicle is classified as a touch-panel operable period and the other period is classified as a touch-panel inoperable period, in the display input unit, andthe information output unit enables access to the optional guidance information during the touch-panel operable period and inhibits access to the optional guidance information during the touch-panel inoperable period. 11. The in-vehicle information system according to claim 10, wherein the information output unit causes superimposed display of information indicating inoperability as information visualized with a predetermined fixed phrase or a predetermined fixed graphic during the touch-panel inoperable period. 12. The in-vehicle information system according to claim 10, wherein the information output unit causes superimposed display of information preannouncing impossibility of touch operations and information prompting the users to ensure security as information visualized with predetermined fixed phrases or predetermined fixed graphics from a timing that is a predetermined period before the touch-panel inoperable period starts. 13. The in-vehicle information system according to claim 2, wherein a plurality of the display input units to which touch operations can be performed are mounted on the vehicle, andthe information output unit automatically returns to the normal information display screen and the normal display operation that is synchronized with a normal information display switching timing of various types of information being displayed on other display input units that have not received a touch operation. 14. The in-vehicle information system according to claim 13, wherein, wherein, when an event requiring display of emergency guidance information to be transferred to the users occurs during an operation of synchronizing switching with the normal information display switching timing, the information output unit prioritizes switching to the emergency guidance information over waiting to synchronize display of the various types of information with the normal information display switching timing. 15.
