Hi, The A7 has 3 sound modes. With the unit on press the speaker button and on the screen it will say either "Headphone sound only" or "Speaker sound enabled". Pressing the speaker button will toggle these modes back and forth. If you don't hear any sound when it says "Speaker sound enabled " it may be that it was wired using the FM Modulator, which means it uses the car speakers. For them to work, turn on your radio and tune it to 87.9 or 88.3. Good Luck!
