- [T\-SB\-0119\-20](/bulletins/10185776.md), 2021-01-25, Service bulletin: BACK OVER PREVENTION:SOFTWARE; STRUCTURE; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM\(GLOBAL POSITIONING SYSTEM\). TSB: Some 2018 ? 2020 model year Toyota vehicles equipped with a Premium Audio with Dynamic Navigation System require a Special Service Tool \(SST\) USB flash drive to update the map, points of interest, and system software. The SST is used with applicable vehicles to deliver the update; however, the process for generating license keys differs from previous generations. Before attempting to perform a map update, the head unit?s expiration date must be checked. If the expiration date is still valid, a license key may be generated without the use of an activation card number. Updating the maps without the use of an activation card number is considered an Embedded Navigation Update \(refer to pg. 10\) and performing this process does not extend the duration of telematic map services. If the head unit?s expiration date is expired, or is expiring within the next 90 days, it should be recommended to the customer to purchase an activation number. Utilizing an activation number will initiate a Dynamic Navigation Update \(refer to pg. 4\). This Dynamic Navigation Update will perform the Embedded Navigation Update and provide telematic map services for a period of two years from the day that the Dynamic Navigation Update is performed. Activation card numbers are provided in an activation card number pamphlet available through the normal parts ordering system. Follow the process in this bulletin to perform the update.
