Symptoms
- Radio display works but no audio plays
- Volume bar moves but nothing is heard
- Other audio sources like Bluetooth also have no sound
- Sound cuts out only on certain stations or sources
Likely causes
- CommonVolume muted or turned all the way downMute can sometimes be toggled accidentally by a steering wheel button or passenger.
- CommonWrong audio source selectedThe system may be set to an input like aux or USB with nothing actually playing.
- PossibleBlown speaker or amplifier fuseA dedicated fuse for the audio system can blow and silence all speakers while the display still works.
- PossibleFailed amplifier or head unitOn systems with a separate amplifier, its failure can cut all sound even if the radio functions.
What to do
- Check that mute isn't engaged, often shown by a small icon or a steering wheel button light.
- Turn the volume up manually rather than relying on remembered levels.
- Confirm the source is set to radio (FM/AM) and not accidentally left on Bluetooth, USB, or aux with nothing playing.
- Test other sources like Bluetooth music to see if the problem is radio-specific or affects all audio.
- Check the fuse box for an audio or amplifier fuse and replace if blown.
- If all sources are silent and the fuse is fine, the amplifier or head unit likely needs professional diagnosis.

When to call a pro
If all audio sources are silent and mute/volume/fuse checks don't help, a mechanic should test the amplifier and speaker wiring.
