If you’re driving a Chevrolet Trax and suddenly your steering wheel voice command button is no longer placing calls—but instead prompts your phone to choose between Bing, Google, or Bixby—you’re seeing a change in how your phone is handling voice assistants.

This can feel unexpected, especially if the feature worked normally before. The good news is that this behaviour is typically related to smartphone settings rather than a change in the vehicle itself. This article explains what’s happening and how to restore the expected voice-command functionality.

What Is Happening When You Press the Voice Command Button?

In the Chevrolet Trax, the steering wheel voice command button is designed to trigger a connected smartphone’s voice assistant when using systems such as Android Auto or Bluetooth voice dialling.

When everything is configured as expected:

• Pressing the button activates your phone’s default voice assistant
• You can say commands like “Call [contact name]”

If your phone now asks you to choose between Bing, Google, or Bixby, it means:

• Your phone no longer has a single default voice assistant set
• The system is asking you to choose which app should handle voice commands

This prompt comes from the phone’s operating system—not the vehicle.

Why This Change Can Happen Suddenly

Even if nothing was intentionally changed, several background updates or settings adjustments can trigger this behaviour.

1. Phone Software Updates

After a system update, some Android devices reset or modify default app preferences. This can include:

• Voice assistant selection
• Default digital assistant app

As a result, the next time the vehicle requests a voice command, the phone asks you to choose again.

2. Multiple Voice Assistants Installed

If your phone has more than one assistant available (for example, Google Assistant and Samsung’s Bixby), the system may require you to:

• Choose a default assistant
• Confirm whether to use it “just once” or “always”

Until you finalize that selection, the prompt will continue to appear.

3. Changes in Android Auto or Bluetooth Permissions

The Chevrolet Trax can interact with your phone through:

• Bluetooth voice dialling
• Android Auto (if equipped and enabled in Canada)

If permissions were updated or reset, the system may:

• Lose its link to the previously selected assistant
• Require reauthorization

4. App Updates or Conflicts

Updates to apps like:

• Google Assistant
• Bixby
• Default browser or search apps

This can affect how voice commands are routed. This can cause the assistant selection prompt to appear instead of executing a command.

Step-by-Step: How to Restore Normal Voice Command Function

To get your Chevrolet Trax voice command button working as expected again, you can follow these steps on your phone:

1. Set a Default Voice Assistant

• Go to your phone’s Settings
• Search for “Default apps” or “Digital assistant app.”
• Select your preferred assistant (typically Google)
• Choose “Always” when prompted

This prevents the system from asking every time.

2. Check Voice Assistant Permissions

• Open your assistant app (e.g., Google Assistant)
• Ensure microphone and phone permissions are enabled
• Confirm voice activation settings are active

3. Verify Android Auto Settings (if used)

• Open Android Auto on your phone
• Check that voice commands are enabled
• Confirm the correct assistant is selected

4. Reconnect Your Phone to the Vehicle

• Disconnect Bluetooth or Android Auto
• Reconnect the device
• Accept any permission prompts that appear

This helps re-establish a clean connection.

5. Test the Voice Command Button

• Start the vehicle
• Press the steering wheel voice command button
• Say a simple command like “Call [contact name]”

If configured correctly, the assistant should respond immediately without asking for app selection.

What to Expect After Fixing the Issue

Once you set a default assistant and confirm permissions:

• Pressing the voice command button should directly activate the assistant
• No selection prompt should appear
• Voice dialling and other commands should function normally

The system should behave consistently across drives.

What Is Normal vs. What Needs Attention

Normal behavior

• Voice assistant activates immediately when pressing the button
• Commands like calling contacts or sending messages work directly
• No repeated prompts for assistant selection

Situations that may require attention

• Repeated prompts to choose between Bing, Google, or Bixby
• Voice assistant not responding after selection
• Delays or interruptions when issuing commands

These typically point to phone-side settings rather than a vehicle issue.

Additional Context: Vehicle vs. Phone Responsibility

It’s important to understand that in the Chevrolet Trax:

• The vehicle provides the input (button and microphone)
• The phone handles the processing (voice assistant and commands)

So when behaviour changes suddenly, it is usually tied to:

• Phone updates
• App settings
• Permissions

The vehicle itself does not control which assistant is used.

Get to Know Your Chevrolet Trax

If your Chevrolet Trax voice command button is asking you to choose between Bing, Google, or Bixby instead of making a call, the cause is typically a change in your phone’s default assistant settings.

Setting a preferred assistant and confirming permissions usually restores normal operation. Once configured, pressing the voice command button should again trigger your assistant directly—allowing you to place calls and use voice features without interruption.
