【Ships within 24 hours】This is the latest nationwide map data update disc for NSZN-Z66T Toyota. I am selling it because I no longer need it. This is the nationwide map update version, the latest 2025 December data CD-ROM disc. By updating the map with this disc on a navigation system with a valid map update expiration date, you will have the latest map (road data, facility information). Updating with this disc, even in just one prefecture, will update the information for highways, toll roads, major national roads, and facilities on highways and toll roads nationwide. You can select and update in increments of 3 prefectures, but the update for the selected prefectures will include some national roads, major roads, prefectural roads, other roads, roads less than 5.5m wide, and notable facilities equivalent to 3D landmarks. The latest data as of the purchase date will be shipped within 24 hours. Please refer to the product images for instructions on how to update using the CD-ROM. ◆Peace of Mind Guarantee ・If the CD-ROM arrives and cannot be read, a replacement CD-ROM will be promptly resent. ・If you purchased the wrong CD-ROM for your model, a CD-ROM for the correct model will be promptly resent, provided you cover the media cost and shipping (flat rate of 300 yen with tracking number). ※In either case, this is limited to navigation systems within the update validity period. ◆Notes Before purchasing, please check that the map update service period is active by operating your navigation system and going to the "Settings" menu → "Map Update" screen. This disc will not update a navigation system whose expiration date has passed. How to check the expiration date: The "End Date" displayed on the "Map Update" screen in the navigation system's "Settings" menu is the update expiration date. If "Outside of Update Service Period" is displayed, you cannot update. Please be sure to check before purchasing, as returns are not accepted due to reasons such as the buyer's navigation system's update expiration date having passed.
