☆ How to check the expiration date
The "Expiration Date" displayed on the "Map Update" screen is the map on-demand validity period.
* Please consider that you cannot update unless the basic map data on the navigation unit is within 2 years and the expiration date has not passed.

Please check the instruction manual for the map update data update procedure.

☆ In addition to map data, VICS traffic congestion display and other features will also be updated to the latest version at the same time.
★Items to be shipped★
