What to Do If There Is No Aux Port in the Car?

[VeraFitz]

If there is no aux port in the car, the solution is to buy a cigarette lighter to aux adapter and connect it to the cigarette lighter. The aux port is an audio input interface that can input audio from electronic audio devices including mp3 players, allowing the car's sound system to output music from these devices. It is an additional signal line design. The aux port establishes a command-line connection between the user and the device, enabling operations that are usually not possible in user mode, such as initialization, restoring default configurations, and correcting abnormal user modes.
