[HarrisonMarie]

Solutions for cars without an AUX port: Purchase a cigarette lighter to AUX adapter and connect it to the cigarette lighter. The AUX port is an audio input interface that can receive audio signals from electronic devices such as MP3 players, allowing the car's sound system to play 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 typically not possible in user mode, such as initialization, restoring default settings, and correcting abnormal user modes.
