【Ships within 24 hours】This is the latest nationwide map data update disc for NSZT-Y68T Toyota navigation systems. I am selling it because I no longer need it. This is the latest 2025 December data CD-ROM disc, the nationwide map update version. By updating the map with this disc on a navigation system with a valid map update period, you will get 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 groups of three 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 three-dimensional landmarks. I will ship the item within 24 hours with the latest data as of the purchase date. Please refer to the product images for instructions on how to update using the CD-ROM. ◆Peace of Mind Guarantee ・If the CD-ROM you receive cannot be read, I will promptly resend a replacement CD-ROM. ・If you purchased the wrong CD-ROM for your model, I will promptly resend the correct CD-ROM for your model if you cover the media cost and shipping fee (300 yen nationwide with a tracking number). ※In both cases, this is limited to navigation systems within the update validity period. ◆Notes Before purchasing, please check that your navigation system is within the map update service period by operating your navigation system and going to the "Settings" menu → "Map Update" screen. This disc will not update a navigation system whose validity period has expired. How to check the validity period: The "End Date" displayed on the "Settings" menu → "Map Update" screen of your navigation system is the update validity period. If "Out of Update Service Period" is displayed, you cannot update. Returns are not accepted due to the buyer's circumstances, such as the update validity period of the navigation system having expired, so please be sure to check before purchasing.
