What to Do If There Is No AUX Port in the Car?
3 Answers
You can purchase a cigarette lighter to AUX adapter online and connect it to the cigarette lighter. The AUX port is an audio input interface that allows audio output from electronic audio devices, including MP3 players, to be connected to the car's audio system for playing music from these devices. Here is additional information: 1. Function of the AUX Port: The AUX port is an additional signal line designed with a single wire. In general audio equipment, besides the standard output and input terminals, there are often several terminals labeled "AUX" as backup connection ports. These can be used for special applications, such as additional audio output or input. 2. Operating Principle of the AUX Port: The multimedia system of the car's computer supports connecting AUX peripherals. When an AUX device is properly connected, you can operate the device to play music. When the system is in AUX mode, the sound output from the audio system is determined by both the connected AUX device and the multimedia volume. If the connected AUX device is muted, the multimedia system will output no sound. Modern smartphones and MP3 players support lossless format music playback.
My old car doesn't have an AUX port either, but I've tried several alternatives over the years. FM transmitters are the most affordable and practical solution - just plug a 20-yuan device into the cigarette lighter, connect your phone via Bluetooth, and it transmits music to your car radio frequency. Though in urban areas with signal interference, you'll need to try several channels. I once bought a car charger with AUX output that plugs into the cigarette lighter, providing a more stable 3.5mm connection than FM. Currently, I mainly use a Bluetooth receiver that fits in the ashtray and can connect two phones simultaneously. There's definitely some audio quality loss, but it's perfectly adequate for podcasts during commutes. The best part is no wiring modifications needed - even beginners can install it effortlessly.
Tried three solutions for my daughter's car: First recommendation is the Lightning to FM transmitter, plug and play for Apple users, also charges. A friend modified the central control unit, costly but smarter with CarPlay. The easiest is actually a Bluetooth speaker in the cup holder, better sound field effect. Special reminder not to buy no-name converters, once I bought a 20-yuan one, the static noise was louder than the voice. Now using a Ugreen receiver with aptX decoding, the car speakers briefly pause when connecting to the phone, but it doesn't affect usage.
