DSZT-YC4T Navigation SD Card 2023 Spring Edition Used with navigation model DSZT-YC4T. Navigation SD card number: 08675-0BD46 Only the navigation SD card and adapter are included. The main unit is not included. There is no receipt. Please purchase if you understand based on the navigation SD number and navigation model. The map has not been updated. The update deadline expired on September 18, 2025. I was able to confirm the map display on another similar navigation system, but the message "(Map SD used in another car has been inserted. Some functions are unavailable)" appeared on the screen. Re-linking is required. Please go to a dealer or research online. I do not know how to handle this, so please purchase only if you understand. I am also selling this on other platforms, so please comment before purchasing in case it has already been sold.
