To use aux in car with phone, you connect your phone to the car's stereo using a 3.5mm male-to-male AUX cable, which lets you play music, podcasts, and navigation audio through the car's speakers. This simple wired connection provides clear, reliable sound without the need for Bluetooth pairing or wireless signals.
What you need to use aux in car with phone
You will need a 3.5mm male-to-male audio cable, commonly known as an AUX cord, to establish the connection. If your phone lacks a 3.5mm headphone jack, you must use a compatible adapter, such as a Lightning to 3.5mm adapter for iPhones or a USB-C to 3.5mm adapter for many Android devices. Ensure you have the correct adapter for your phone model before attempting to connect.
Connecting your phone to the car's aux input
- Plug one end of the 3.5mm AUX cable into your phone's headphone jack, or into the adapter connected to your phone.
- Plug the other end of the AUX cable firmly into the car's AUX input port. Consult your car's manual if you're unsure of the precise location of the aux input port.
- On your car's stereo system, select "AUX" or "Line In" as the audio source, often by pressing a "Source" or "Media" button. You may need to switch to the auxiliary input mode using the car's audio controls or the dashboard settings.
Once these steps are complete, any audio playing from your phone will route through the car's speakers.
Adjusting the volume and audio settings
Start with the volume low on both your phone and the car stereo. If the sound becomes distorted, lower the volume on your phone slightly. Some car audio systems offer equalizer settings that allow you to adjust bass, treble, and balance for clearer sound. If you find that the audio is distorted or the bass is too heavy, you can adjust the equalizer settings on your phone or the car's audio system. On most audio systems, you can access the equalizer by going into the audio settings menu. Experiment with different equalizer presets or manually adjust the frequency and intensity of the sound to suit your preference. Some car audio systems also offer additional audio enhancements such as surround sound, virtual soundstage, or bass boost. Explore these options if available and adjust them as per your liking. If you are using a music streaming app or media player on your phone, you can also check the sound settings within the app. Some apps provide options to toggle features like sound normalization or audio enhancement, which can further enhance your audio experience. Test the audio at different driving speeds to ensure it remains clear and audible.
Making Hands-free Calls using the Aux Input
To make hands-free calls using the aux input, you will need a few additional tools. Firstly, ensure that your phone is connected to the car's aux input using the appropriate audio cable. Once connected, follow these steps: Open your phone's settings, and navigate to the Bluetooth section. Enable the Bluetooth function if it's not already turned on. Ensure that your car's audio system is set to the aux input mode. In your phone's Bluetooth settings, scan for available devices. Your car's audio system should appear on the list. Select your car's audio system from the list of available devices. Once connected, your phone should indicate that it is paired with the car's audio system. Make sure that your phone's media audio is enabled and the volume is turned up. During a call, you can adjust the call volume using the controls on your car's audio system. Some car models may also provide additional features such as call transfer, call waiting, or caller ID display on the car's screen.
What if your car doesn't have an aux input
If your car does not have an AUX input, a standard AUX cable cannot be used. Alternative solutions include a Bluetooth receiver that plugs into the car's power or an FM transmitter. For drivers seeking a wireless option, FM transmitters for cars broadcast audio from your phone to an unused FM radio frequency, allowing playback through the car's existing radio speakers without any wiring. These devices are especially useful for older vehicles without aux ports or Bluetooth.

What kind of cable do I need to connect my phone to the car's aux input?

Do I need an adapter for a phone without a headphone jack?
Yes. iPhones require a Lightning to 3.5mm adapter, while most Android phones without a headphone jack need a USB-C to 3.5mm adapter. These adapters are sold separately and are not included with the AUX cable.
