2021 Hyundai Wireless CarPlay Disconnection Software Update

Q: What is the primary cause of the Hyundai Wireless CarPlay disconnection issue?

The intermittent Wireless CarPlay disconnection issue in 2021 Hyundai models is primarily caused by Apple iOS software intermittently pausing data transmission, which interrupts communication between the radio and CarPlay.

Owners of certain 2021 Hyundai Elantra, Sonata, Palisade, and Venue models equipped with display audio may experience intermittent Wireless CarPlay disconnections. This issue is detailed in Hyundai Technical Service Bulletin (TSB) 21-BE-002H, which outlines a software update designed to reduce these occurrences.

Symptoms

When using Wireless CarPlay, the system may unexpectedly disconnect. This disconnection is typically accompanied by a pop-up message on the radio screen stating, "Phone Not Responding. Please reconnect it and try again". This can interrupt navigation, music playback, and communication features.

Diagnosis / Trigger Conditions

The TSB indicates that the disconnection phenomenon is primarily caused by Apple iOS software intermittently pausing data transmission. This interruption leads to communication issues between the vehicle's radio and the CarPlay system. The software update provided by Hyundai aims to mitigate these disconnections until Apple releases its own software update to fully correct the condition.

Repair Procedure Summary

The repair involves updating the radio software using a specific USB stick. The general steps are:

Turn the engine ON and wait for the radio to fully load.
Access the system information screen by pressing and holding the SETUP button, then selecting "SW Info/Update" if prompted.
Verify the current software version matches an older version listed in the TSB's software table. If it does not match, the update should not be performed.
Insert the correct Software Update USB stick, specific to the vehicle model, into the USB port.
Press the 'Update' button on the screen to begin the process.
Confirm the last six digits of the new software version on the screen match the new version listed in the TSB's table and select 'YES' to start.
The update will take approximately 15 minutes. Once completed, the system will restart, and the radio mode screen will display.
After the update, confirm the new software version matches the table. If not, ensure the correct USB was used and repeat the process.
Remove the Software Update USB from the port.
