How to reset the car radio to factory settings?

Press the RESET button on the front panel (often a small hole) with a pointed object. This will erase all stations and custom settings.

Why is the sound low or distorted?

Check the volume, balance, and fader settings. Ensure the speakers are compatible with the impedance (usually 4 ohms). If the problem persists, test with another audio source.
