- [23TC08\_Region Le](/bulletins/10251752.md), 2024-03-18, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. RL: One of the features in your vehicle is the predictive efficient drive system. This system uses the navigation system to predict likely deceleration or stopping locations based on the driving situation and traffic patterns, to enhance fuel economy. However, for some vehicles, the navigation system may not learn these driving patterns due to a programming error in the skid control ECU.

- [T\-SB\-0039\-20 Rev](/bulletins/10183284.md), 2020-11-30, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. TSB: An initialization procedure is required to activate the Entune? 3.0 App Suite Connect for Audio, Audio Plus, and Premium Audio head units before they are used for the first time on new vehicles. The initialization procedure may also be performed under other circumstances, such as following a head unit replacement or after the customer?s personal settings are erased. The initialization procedure requires between 3 and 15 minutes to complete, depending on file size, cellular connection speed, and other factors. Following the initialization procedure, individual Entune? 3.0 apps may periodically update through an over\-the\-air update system. Updates are either optional or mandatory. The update procedure will take approximately 1 minute for each app requiring an update. Follow the Initialization/Update Procedure in this bulletin to perform the initialization and app updates.
- [T\-SB\-0047\-19 Rev](/bulletins/10179765.md), 2020-09-14, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; 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.
