Yes, it is important to have a headrest in the car for safety reasons. A headrest helps to prevent whiplash in the event of a rear-end collision by supporting the head and neck. It also provides comfort and support for passengers during long drives, reducing the risk of neck strain and fatigue. Therefore, it is recommended to have a properly adjusted headrest in the car for both safety and comfort. **

To replace a car's headrest, first, adjust the headrest to its highest position. Then, locate the release button or lever at the base of the headrest and press or pull it to release the headrest from the seat. Once the headrest is released, simply pull it out of the seat and insert the new headrest by aligning the metal rods with the slots in the seat and pushing it in until it clicks into place. Finally, adjust the new headrest to the desired position. **

Some car radios have a feature that automatically switches to news stations when they detect a news broadcast. This feature is often found in newer car models and can be activated through the radio settings. However, not all car radios have this feature, and it may depend on the specific make and model of the car. If you are interested in this feature, it's best to check the specifications of your car's radio system or consult the owner's manual for more information. **

Make sure to check the dimensions and specifications of the headrest to ensure it will fit your chair properly. **

If you are using a streaming service or your phone to play music, you can disconnect or pause the news app or station you were listening to. If your car has a separate volume control for the radio and music, you can also lower the volume or mute the radio news while keeping the music playing. **
