• How do I pair my phone with the SONRU Bluetooth FM transmitter?

  Plug the transmitter into your car's power outlet. Tune your car radio to an unused FM frequency (static sound). Set the SONRU transmitter to the same frequency. Then, open Bluetooth settings on your phone, search for the device (often named 'SONRU' or similar), and pair.

• Why do I hear static noise when using the FM transmitter?

  Static noise is typically caused by radio frequency interference. Try tuning both your car radio and the transmitter to a different, completely empty station where there is no broadcast signal.

• Does the SONRU car charger support fast charging?

  Yes, many SONRU car chargers are equipped with PD (Power Delivery) and QC3.0 (Quick Charge) ports, allowing compatible devices to charge significantly faster than standard chargers.

• My SONRU device is not working. How do I contact support?

  For warranty claims or technical support, SONRU advises contacting their support team via email at sales-us@sonrudirect.com (US) or sales-uk@sonrudirect.com (UK).
