What to do if the car AUX connection to the phone doesn't work?

If the car AUX connection to the phone has no response, it may be due to an unsuitable cable or plug. In such cases, try replacing the cable. More information about car AUX is as follows: 1. Interface location: The position of the car AUX interface varies by vehicle, but like the headphone jack, it is usually marked with the letters 'AUX' nearby, making it easy to find. Additionally, remember to set the car audio system's input mode to AUX after connecting. 2. Function: Connecting the phone to the AUX interface allows the phone's audio to be played through the car speakers, enabling hands-free calls and listening to MP3s on the phone. The phone can be connected even if it lacks a 3.5mm headphone jack by using an adapter for the phone's port to a 3.5mm headphone jack, which can be purchased online. Then, connect one end of the cable to the phone's headphone port and the other end to the car's 'AUX IN' port. Press and hold the 'CD/AUX' button until 'AUDIO IN' appears, adjust the volume, and playback will begin.
I often encounter this issue when repairing cars: the AUX port not playing music from the phone is usually due to simple faults. First, check your AUX cable. If the cable is aged or damaged, the signal won't reach the car speakers—try replacing it with a new one. The phone is also responsible; open the settings to confirm the volume is turned up and the AUX output mode is selected. The car's AUX port might be dusty or corroded—gently clean it with a cotton swab dipped in alcohol, and it should work. Don't rush to the repair shop; try plugging another phone into the AUX port. If it plays, it confirms the issue is with your phone. Related experience suggests that older cars are particularly prone to this fault. Regularly cleaning the port during maintenance can prevent it from happening again, and the problem is usually resolved quickly this way.
