Bluetooth connects but no audio

When Bluetooth shows connected but you hear nothing, the issue is usually the audio source setting or volume on one side, not a broken connection.

Symptoms

  • Phone shows connected to the car
  • Calls or music don't play through car speakers
  • Sound may still play through the phone itself
  • Works for calls but not music, or vice versa

Likely causes

  • CommonWrong audio source selected in the carThe infotainment system may be set to radio, USB, or another input instead of Bluetooth audio.
  • CommonPhone media volume muted or very lowBluetooth call and media volumes are often separate and one can be turned down without notice.
  • PossibleOnly phone (hands-free) profile connected, not media profileSome pairings only enable calls (HFP) without also enabling music streaming (A2DP).
  • PossibleApp playing audio through the phone speaker instead of BluetoothCertain apps default to the phone's speaker unless manually switched.

What to do

  1. On the car's screen, make sure the audio source is set to Bluetooth/phone audio, not radio or USB.
  2. Turn up both the car's volume and the phone's media volume separately.
  3. Remove and re-pair the phone, making sure to allow both 'phone calls' and 'media audio' permissions during pairing.
  4. In the phone's Bluetooth settings, tap the connected car entry and confirm media audio is toggled on if that option exists.
  5. Test a phone call and a music app separately to narrow down whether it's a call-only or media-only issue.
  6. Restart both devices if the issue persists after checking sources and permissions.

When to call a pro

If audio still won't come through after re-pairing and checking sources, a dealer can check for a Bluetooth software update.
