Hi Claudia Many radio/stereos have inputs, sometimes specified for MP3 players, but sometimes also called "Auxiliary" input etc. Also many T.V.s have "AV" or auxiliary inputs, two audio and 1 video. These can also work fine.
The only type of inputs to which you shouldn't connect the MP3 player would be those for microphones or old fashioned record players. The connectors can come in two types, modernly, an 1.8Th inch earphone jack just like the jack for earphones on your MP3 player. Other units may have two RCA type jacks. Whichever you find radio shack will have the appropriate cord to join them up. One tip, after you connect things up, and learn which if any switch settings to use, try to keep the volume on the radio slightly higher , and the volume on the MP3 player slightly lower. since both controls effect what you hear. This will tend to reduce any distortion in the system. Tom Fowle
