How to Eliminate Bluetooth Noise in Car Cigarette Lighter?

[McHannah]

To eliminate Bluetooth noise in the car, first check if there is any foreign object inside the earphone. Use a cotton swab dipped in alcohol to clean the earphone plug, then wipe it dry with a tissue. Alternatively, twist the earphone wire to see if the noise changes with the movement. If it does, the earphone wire may be faulty and needs replacement. Below are the functions of the car's Bluetooth system: 1. The main function is to connect with a mobile phone via Bluetooth technology for hands-free calls while driving, reducing the risk of traffic accidents. It automatically recognizes mobile phones and connects without the need for cables or phone holders. 2. If you choose to make calls through the car's audio system, the audio will automatically mute when receiving or making a call, and the conversation will be transmitted through the audio system's speakers/microphone. If you choose to use a Bluetooth wireless headset for calls, simply press the answer button when a call comes in, provided the headset is powered on.
