This is an Dongben Civic. Can I listen to music by plugging in MP3 directly? Do you need to buy wiring or something? Can I plug in a USB flash drive to listen to music? Please elaborate. Thank you questioner: Sue's best answer took the following steps: 1. Unplug the cigarette lighter, insert the car mp3 into the cigarette lighter socket, and wait for the indicator light on the MP3 to light up; 2. Insert the audio input plug of mp3 audio converter into your MP3 headphone jack, and press the FM part of the radio according to the FM number displayed on the screen; 3. Press the leftmost up and down keys below to adjust it to the same number as MP3 frequency. Because the car MP3 works by sending FM signals, the car stereo can only receive signals if it is tuned to FM band instead of AM band, so it needs to be tuned to the same frequency. For example, generally speaking, the car MP3 transmits 88.75MHZ, so you only need to adjust the frequency of the car stereo to 88.70MHZ. Press and hold the button you selected in 1-6 of the selected radio for more than three seconds. It will be saved after hearing the click. At this time, you can listen to MP3 songs on the frequency here. Next, you can adjust the volume to your satisfaction according to your own habits. Million car purchase subsidy
