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.
