2018-2024 Toyota Premium Audio Navigation Map Update TSB

Toyota Technical Service Bulletin T-SB-0106-22 Rev2, issued on December 7, 2022, provides comprehensive instructions for updating the navigation system in many 2018-2024 Toyota models equipped with Premium Audio and Dynamic Navigation. This update ensures that vehicles have the latest map data and system software, improving navigation accuracy and functionality. The bulletin details two primary update methods: Dynamic Navigation Update, which extends dynamic map services, and Embedded Navigation Update, which updates map data without extending services.

Symptoms of Outdated Navigation Maps

Owners may notice that their vehicle's navigation system displays outdated road information, points of interest, or lacks new routes. This indicates a need for a map update. Additionally, if the dynamic navigation services are expiring or have already expired, an update is recommended to restore full functionality. For example, if you own a 2024 Toyota Camry, an outdated navigation map update could lead to incorrect routing or missing new roads.

Diagnosis and Update Conditions

To determine if an update is needed, technicians must check the expiration date of the dynamic subscription stored in the head unit. An update is recommended if the subscription has expired or is expiring within the next 90 days. For a Dynamic Navigation Update, an Activation Card Number (ACN) is required, which also extends dynamic map services for two years. An Embedded Navigation Update does not require an ACN and does not extend dynamic services.

Required Parts and Tools

Performing a navigation map update requires specific parts and special service tools:

• NAV ACN Card V.20.00 (Part Number: 86271-HDD09-00): Required for Dynamic Navigation Updates to extend dynamic map services.
• USB Drive Navigation Update – AWTEC* (Part Number: TLAW-SD017-24F): This is an essential Special Service Tool (SST) USB flash drive containing the map data and software. Additional SSTs can be ordered by calling 1-800-368-6787 or by visiting Home – Service Resources – Toyota Special Service Tools (SSTs).

Important Warnings and Notes

Owners and technicians should be aware of several critical points outlined in the TSB:

• Superseded Bulletin: The information in this bulletin supersedes Service Bulletin No. T-SB-0119-20. Service Bulletin No. T-SB-0119-20 is obsolete and any previous printed versions should be discarded. The applicability has been updated to include 2021–2022 model year Toyota vehicles, and further revisions in Rev2 (February 11, 2025) included 2022 Corolla Cross, 2023 Tacoma, and 2023-2024 Camry, 4Runner, and Sienna Hybrid vehicles.
• SST Storage: The SST USB flash drive containing map data is released annually and MUST be stored in the SST cabinet to ensure it can be easily found.
• Update Process Sensitivity: If ANY of the navigation data is entered incorrectly during the update process, the update will NOT complete successfully, and it is possible a NEW ACN will be required, potentially incurring additional costs.
• USB Drive Handling: Do NOT remove the USB flash drive during this process. Removing it prematurely can interrupt the update and potentially cause issues with the head unit.
• Ignition Cycle: The head unit will prompt to cycle the ignition (OFF then ON, or
