2021-2022 Toyota Navigation System Update TSB

Owners of 2021-2022 Toyota vehicles equipped with the Premium Audio with Dynamic Navigation System may need to update their map data, points of interest, and system software. This process requires a specific Special Service Tool (SST) USB flash drive. Understanding the difference between an Embedded Navigation Update and a Dynamic Navigation Update is crucial for ensuring your system is current and for managing your subscription.

What Owners Should Know

Before performing any update, it's important to check the expiration date of your dynamic subscription, which is stored in the head unit of your vehicle. If your subscription has not yet expired, you might be able to generate a license key without needing to purchase an Activation Card Number (ACN). This is referred to as an "Embedded Navigation Update" and does not extend your dynamic map services subscription.

However, if your subscription has already expired, or is set to expire within the next 90 days, Toyota recommends purchasing an ACN. Using an ACN initiates a "Dynamic Navigation Update," which not only performs the embedded navigation update but also extends your dynamic map services for two years from the date of the update. This ensures you continue to receive the latest map data and features for your Toyota navigation system update.

Repair Procedure Summary

Dealers will use a Special Service Tool (SST) USB flash drive to deliver the necessary updates to the Premium Audio with Dynamic Navigation System. The process for generating license keys for these updates has been revised compared to previous generations.

For vehicles with an active dynamic subscription, a license key can be generated without an ACN, performing an "Embedded Navigation Update." This update focuses on the map and system software but does not prolong the subscription period for dynamic services. If the subscription is expired or nearing expiration, an ACN is required. The ACN facilitates a "Dynamic Navigation Update," which includes the embedded update and provides an additional two years of dynamic map services.

Required Tools or Parts

To perform the necessary updates for the Toyota navigation system update, technicians will utilize a Special Service Tool (SST) USB flash drive. For extending dynamic map services, an Activation Card Number (ACN) is required. These ACNs are provided in a pamphlet and can be ordered through the standard parts ordering system.

Owner Action

If you believe your 2021-2022 Toyota's Premium Audio with Dynamic Navigation System requires an update, or if you are unsure about your dynamic subscription status, contact your authorized Toyota dealer. They can check your subscription expiration date and advise whether an Activation Card Number (ACN) purchase is recommended for a "Dynamic Navigation Update" to extend your services. Ensure your Toyota navigation system update is handled by a qualified technician.
