When you buy a new car, you’re likely to get a radio. But what kind of radio? There are many different types of radios available, and it’s important to choose one that will work with your car’s specific settings. To test a radio, first make sure it’s working properly. Open the door of your car and plug the power cord in to an outlet. Turn on your car’s headlights and music player. If everything is working correctly, the radio should be able to pick up sound from both devices. If not, try changing the channels or adjusting the volume. If you’re buying a new car, be sure to get a model with an aux input so you can use your phone as an audio player. Many cars also come with Bluetooth capabilities so you can control music and other devices without having to take your hands off the wheel.
