- [TSB010622](/bulletins/10252259.md), 2024-04-01, Service bulletin: EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM\(GLOBAL POSITIONING SYSTEM\); UNKNOWN OR OTHER. TSB: Some 2018 ? 2022 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 expiration date of the dynamic subscription \(stored in the head unit\), must be checked. If the expiration date has not passed, a license key may be generated without the purchase of an Activation Card Number \(ACN\). Updating the map without the use of an ACN is considered an Embedded Navigation Update \(refer to pg. 10\) and performing this update does not extend the subscription to dynamic map services. If the subscription period has expired, or is expiring within the next 90 days, it should be recommended to the customer to purchase an ACN. Utilizing an ACN, will initiate the Dynamic Navigation Update \(refer to pg. 4\). This Dynamic Navigation Update will perform the embedded navigation update and provide dynamic map services for a period of two years from the date that the Dynamic Navigation Update is performed. ACNs are provided in a pamphlet available through the normal parts ordering system. Follow the process in this bulletin to perform the update.

It is recommended to disable the PCS and DRCC systems on vehicles that have been modified \(ride height, oversized wheels/tires, brush bars, etc.\) in a way that potentially disrupts the functionality of these systems. Vehicle owner?s written consent is required before performing the calibration to permanently disable the PCS and DRCC systems.
