One reason an incompatible audio jack causes issues is if the audio jack is the wrong size for your car’s aux port. It won’t fit properly, and you won’t get any sound. For instance, if your car’s aux port needs the standard 3.5mm jack, but you have a 2.5mm jack, it won’t fit correctly. As a result, you won’t hear any audio. Also, the number of conductors in the audio jack can impact compatibility. Some audio jacks have only two conductors, while others have three or four.

The metal contacts that connect the audio cable to the port become corroded, which causes the signal to be interrupted or lost entirely. This can result in no sound or distorted sound when attempting to use the aux port. Also, corrosion can damage the internal components of the aux port. If the corrosion is severe enough, it can cause the metal surfaces to deteriorate, leading to broken wires, damaged circuits, or other internal damage. This can result in the aux port failing to work altogether. Lastly, corrosion can prevent the auxiliary jack from properly inserting into the car radio.
