Set up your Google Assistant car accessory

With a Google Assistant car accessory, you can use the Google Assistant in any car that has a Bluetooth connection or AUX plug.

For now, the iPhone experience for the Google Assistant car accessory is in beta with limited capabilities. We are developing improvements and new features.

What you need

  • A car with a Bluetooth connection or AUX plug
  • An iPhone running the Google Assistant app version 1.5.7107 or higher

Note: For now, your Google Assistant car accessory won't work with an iPhone 6.

Car accessory won’t respond
  1. If your car accessory won’t respond to your voice, press the button on the device.

  3. On the car accessory, press and hold the button until the lights turn off for a few seconds and then turn blue.
  4. On the car accessory, press and hold the button for about 12 seconds. The lights will turn off for a few seconds and then turn blue.

  7. iPhone only: Under "Assistant devices," tap your car accessory and then Remove your Google Assistant.
No AUX input or Bluetooth

If your car doesn’t have an AUX input or Bluetooth playback, you can try connecting your Google Assistant car accessory with an FM transmitter or a cassette adapter. To use a cassette adapter, your car must have a cassette player.

Either piece of equipment must be connected to your Google Assistant car accessory using the 3.5mm output. Then choose the AUX option during setup.
