[DiJohnny]

To switch from AM to FM on a car radio, you can use the left or right arrow keys to slide left or right. The car radio is a voice entertainment configuration installed in the car and is one of the common configurations of the car audio-visual entertainment system. AM is medium wave, with relatively lower sound quality, capable of receiving medium and long-distance signals; FM is frequency modulation stereo, with better sound quality, but can only receive local signals. A radio is a machine composed of mechanical devices, electronic components, magnets, etc., which converts radio wave signals into electrical energy and can receive audio signals transmitted by radio stations. It is also known as wireless or broadcast. When using spatial fields to transmit information, it must be an RF signal to ensure the transmission distance is sufficiently far.
