 "content_markdown": "> QUICK ANSWER\n>\n> **Toyota Tech Tip T-TT-0803-26 (May 21, 2026) covers intermittent audio, CarPlay and Bluetooth problems on 2026 RAV4 Hybrid and Plug-in Hybrid vehicles with head unit version 1136 or older.** The symptoms are no sound from the JBL system at startup, CarPlay audio and icon missing, CarPlay not launching at restart, Bluetooth not pairing after a remote start, and Sirius XM seek buttons misbehaving. Toyota says the conditions are **under investigation** and **replacing the head unit will not fix them**. Its temporary fixes: press the power/volume knob twice for JBL audio, and toggle CarPlay or Bluetooth off and on in the head unit's settings. A later service bulletin, [T-SB-0050-26](/guides/toyota-t-sb-0050-26-rav4-head-unit-software-update/), is a head unit software update.\n\nIf your 2026 RAV4's CarPlay drops or the speakers are silent at startup, this tech tip describes it. A dealer that says it has never heard of the problem can look up T-TT-0803-26.\n\n## The Symptoms Toyota Lists\n\nSome 2026 RAV4 Hybrid and Plug-in Hybrid vehicles with head unit versions **1136 or older** may show one or more of these intermittent conditions:\n\n- No sound from the JBL audio at startup\n- CarPlay audio and the CarPlay icon are inoperative\n- CarPlay does not launch automatically at vehicle restart\n- A Bluetooth device does not pair automatically after a remote engine start from the app or key fob\n- Steering wheel seek switches do not work as expected on Sirius XM after transferring favorite stations from an older account to the vehicle\n\n## Toyota's Temporary Fixes\n\nToyota's tech tip says to temporarily recover as follows:\n\n- **JBL audio silent at startup:** press the power/volume knob twice (off, then on).\n- **CarPlay:** toggle the CarPlay device off and on in the head unit's settings menu (Settings, Bluetooth and Devices).\n- **Bluetooth after remote start:** toggle the Bluetooth device off and on in the same menu.\n- **Sirius XM seek switches:** tap the heart icon on favorite stations that show an empty heart.\n\n## What Toyota Says About a Permanent Fix\n\nThe tip says the conditions are **still under investigation** and that **replacing the head unit will not repair them**. It does not describe a software fix. Toyota later released [T-SB-0050-26](/guides/toyota-t-sb-0050-26-rav4-head-unit-software-update/), a head unit software update, version 8612G42397, which lists other infotainment fixes. The two documents are separate. Ask your dealer whether the update applies to your symptoms. The tech tip carries an expiry date of August 21, 2026, which is how Toyota ages its tech tips and does not mean the problem went away.\n\n## Frequently Asked Questions\n\n### What is T-TT-0803-26?\n\nA Toyota Tech Tip dated May 21, 2026, on intermittent audio, CarPlay and Bluetooth issues on 2026 RAV4 Hybrid and Plug-in Hybrid vehicles with head unit software 1136 or older.\n\n### Will a new head unit fix my RAV4's CarPlay?\n\nToyota says replacing the head unit will not repair these conditions, because they are software-related.\n\n### How do I reset CarPlay on a 2026 RAV4?\n\nToyota's temporary fix is to toggle the CarPlay device off and on in the head unit's Bluetooth and Devices settings.\n\n### Is there a software update?\n\nToyota released head unit software 8612G42397 under [T-SB-0050-26](/guides/toyota-t-sb-0050-26-rav4-head-unit-software-update/).
