Start the assistant with the car parked and look at the phone's output selector. Music and assistant replies may use different audio routes.
Use normal shutdown procedures, keep hardware dry and stop if you see damage, overheating, burning smells or any electrical risk.
Checks to perform in the right order
Confirm the exact symptom
Confirm the car is connected for media or hands-free audio according to the assistant's behavior.
Start with the simplest reversible check
Select the vehicle output while the assistant is speaking and note whether the route remains there.
Change one variable at a time
Compare a phone call and a music track to determine which Bluetooth profile is missing.
Cross-test before resetting anything
Write down what changes and what stays the same. A controlled comparison is more useful than several resets performed together.
Escalate with useful evidence
If the problem survives the safe checks, record the model, software version, warning shown and tests already performed before contacting support.
How to narrow down the cause
- A change after one controlled test is a useful clue; keep the other variables unchanged.
- If a second compatible device works in the same setup, focus on the first device rather than replacing everything.
- Stop if there is heat, liquid, physical damage, burning smell or electrical risk.
Official sources used
Procedures can vary by model, firmware or hardware revision. When your device differs, use the official manufacturer documentation for that exact model.
