2021-2023 Hyundai Apple CarPlay Google Maps Delay TSB

Owners of certain 2021-2023 Hyundai vehicles may notice a significant delay when using Google Maps through Apple CarPlay. This issue, identified in TSB 23-BE-007H, can lead to a frustrating navigation experience. Hyundai has released a software update designed to specifically address this problem, improving the performance of Google Maps within Apple CarPlay.

Symptoms

The primary symptom owners will experience is a noticeable delay in Google Maps functionality when utilizing the Apple CarPlay service. This can manifest as slow map rendering, delayed route updates, or a general unresponsiveness of the navigation interface. The Hyundai Apple CarPlay Google Maps delay can hinder effective navigation and user experience.

Diagnosis and Trigger Conditions

The root cause of the Hyundai Apple CarPlay Google Maps delay has been identified as data congestion. The current version of Google Maps transmits approximately ten times more data compared to its previous iteration. This increased data transmission overwhelms the system, leading to the observed delays. To counteract this, Hyundai's software update incorporates a "frame skip logic" designed to manage and resolve this data congestion.

Important Warnings for Owners

Hyundai has issued specific guidance regarding this issue:

• Warranty Coverage: This bulletin is informational and intended for dealers to assist customers upon request. The procedure outlined within this bulletin is explicitly stated as "not covered by Hyundai warranty and customer expense may apply." Owners should be aware that they might incur costs if they seek dealer assistance for this update.
• Warranty Claims: Hyundai advises, "Instead of submitting a Warranty claim, the update should resolve the issues with the Apple CarPlay app." This indicates that owners are encouraged to perform the update themselves or understand that a warranty claim for the delay itself may not be accepted if the update is the prescribed fix.

Repair Procedure Summary

The resolution for the Google Maps delay involves updating your vehicle's Apple CarPlay software. This is a self-service procedure that can be performed by the owner using a USB drive. The process is as follows:
