CAR-MOUNTED INFORMATION DISPLAY DEVICE AND INFORMATION DISPLAY METHOD

摘要

A first navigation system display (10) and a second navigation system display (20) are pre-installed inside a vehicle cabin. A judgment is made as to whether the content displayed by the first navigation system display (10) and the content displayed by the second navigation system display (20) are the same. If the two sets of information are judged to be the same, from among the first navigation system display (10) and the second navigation system display (20), the content displayed on the display which was the first to display the content deemed to be the same is switched to other content pre-associated content to the content deemed to be the same.
