Why is my Bluetooth connected to my car but won t play music?

When your phone shows a Bluetooth connection to the car but no music comes through, the fix is usually a matter of audio routing or a simple setting. Most often, the problem lies in whether the car is using a hands-free profile versus a media profile, or in a few quick phone or car settings that can be adjusted in minutes.


What’s happening when Bluetooth shows connected but won’t play music


Bluetooth on phones uses multiple profiles to handle different kinds of audio. If the car is linked as a hands-free device instead of a media playback device, you’ll hear nothing from the car speakers even though it’s connected. Other common culprits include the car’s playback mode, the phone’s audio routing, app-specific issues, and outdated software. The list below covers the scenarios most people encounter with iPhone, Android, and a range of car brands.



  • A2DP vs HFP mismatch: The car might be connected as a phone headset (HFP) rather than a stereo speaker (A2DP). When connected via HFP, music playback to the car speakers may be blocked or routed to a mono or limited channel.

  • Car head unit not set to Media: Some dashboards require you to explicitly choose a media or Bluetooth audio source on the display; simply pairing does not always switch the car into audio playback mode.

  • Phone Bluetooth settings disable Media Audio: On Android, ensure the car is allowed to use Media audio in Bluetooth settings; on iPhone, verify the car entry shows the correct media output.

  • Music app or service routing issue: The app may be paused, muted, or using a different output path; check the app’s playback controls and the device’s volume.

  • Multiple connected devices: If another Bluetooth device is connected, audio may be routed there instead of the car.

  • Outdated software or firmware: Older car firmware or phone OS can create compatibility gaps with newer cars and apps.

  • Codec or format limitations: Some cars can’t handle certain codecs or streaming formats, which can block playback.

  • Notifications or calls interrupting audio: Incoming calls or alerts can briefly take over the audio path and leave playback suspended.


In most cases, adjusting the car’s source selection, re-enabling media audio, and re-pairing resolves the issue. If not, a structured troubleshooting approach helps identify the specific cause.


Troubleshooting: step-by-step


Use these steps in order to diagnose and fix the problem. They apply to common iPhone and Android setups, with notes for car-specific quirks.



  1. Make sure the car head unit is set to play Bluetooth audio, not just phone calls. On the car display, select "Media" or "Bluetooth Audio" as the audio source.

  2. On your phone, verify that the car is allowed to play media audio.

    For Android: Settings > Bluetooth > your car > gear icon > enable "Media audio".

    For iPhone: Settings > Bluetooth > tap the car > ensure "Media" is enabled and that the car is selected as Output.

  3. Test with a different music app or streaming service to confirm the issue isn’t isolated to one app; ensure the app’s playback and volume are active on both the phone and car.

  4. Check volume and mute status on both devices. Make sure neither the phone nor the car is muted and that the media volume is turned up.

  5. Disconnect other Bluetooth devices and re-pair the car. In your phone’s Bluetooth settings, “Forget” the car, then re-pair it from scratch.

  6. Restart devices. Reboot your phone and cycle the car’s infotainment system (or restart the car’s computer) to clear temporary glitches.

  7. Update software. Install any available updates for your phone OS, the music app, and the car’s firmware to improve Bluetooth compatibility.

  8. Try a wired connection (AUX or USB) if available. If wired audio works but Bluetooth does not, the issue is likely Bluetooth-related rather than your music service.

  9. If problems persist, consult the car’s manual or dealer service. There may be a known compatibility issue with your phone model or a required reset of the head unit.


Following these steps resolves the majority of Bluetooth-audio playback problems. If the issue remains, there may be a hardware fault or a deeper software incompatibility that requires professional support.


Brand-specific notes


Some car brands have particular quirks (for example, a “Media” toggle in the Bluetooth settings or a requirement to reconnect after an OS update). If you repeatedly encounter trouble, consult the vehicle’s owner manual or the manufacturer’s online support for model-specific steps.


Summary


When your phone shows a Bluetooth connection to your car but music won’t play, the root causes are usually audio routing, source selection, or pairing issues rather than the music itself. By ensuring the car is in Media/Bluetooth Audio mode, enabling the phone’s Media Audio for the car, re-pairing, and keeping software up to date, most users can restore streaming audio. If necessary, a wired connection can help confirm whether the problem is Bluetooth-specific or broader, and professional support may be needed for persistent hardware-related faults.

Why isn't my Bluetooth working when it says connected?


If Bluetooth is connected but not working, restart both devices, check the audio output settings to ensure the correct device is selected, and try removing and re-pairing the Bluetooth device.

Why is my Bluetooth connected to my car but not playing?


Your Bluetooth might be connected but have no sound because the wrong audio source is selected, the volume is too low on either the phone or car, or there is a temporary glitch. To fix this, first check that the car's audio source is set to Bluetooth and that the volume is up on both your phone and car, then try toggling Bluetooth off and on or restarting both devices. If the problem persists, re-pairing the devices, checking for software updates, or resetting your phone's network settings may help.
