How to fix bluetooth static in car?

In order to resolve Bluetooth static, restart your phone and car’s infotainment system first. Unpair and re-pair the connected devices. Check for interference from nearby electronics or physical obstructions. Also, check for software updates on your devices.

If your Bluetooth transmitter is not built-in, sometimes that can also cause Bluetooth static. In that case, try a different one. If the issue persists, consult a dealer or mechanic. If the noise is a constant background hiss, then it is not static, but white noise, which might be a feature of your car’s audio system.
