【Ships within 24 hours】This is a Toyota latest nationwide map data update disc for NSZT-W66T. 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 increments 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 prominent facilities equivalent to three-dimensional landmarks. The latest data as of the purchase date will be shipped within 24 hours. Please refer to the product images for how to update using the CD-ROM. ◆Peace of Mind Guarantee ・If the CD-ROM you receive cannot be read, a replacement CD-ROM will be promptly resent. ・If you purchased the wrong CD-ROM for your model, we will promptly resend the correct CD-ROM for your model if you cover the media cost and shipping (flat rate of 300 yen with tracking number). ※In both cases, 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 navigation systems that have passed their expiration date. How to check the expiration date: The "End Date" listed on the "Map Update" screen in the navigation system's "Settings" menu is the update validity period. If "Out 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 validity period having expired.
