Infinity CD player jammed. Stays on even when cars off

@George_San_Jose1 but with aux all you have is a cord and you can listen to anything with just the phone

If you mean using your cell phone to play a cell-phone mp3 file, and listening to the audio output via the aux input to the car’s stereo, yes, that method also uses no moving parts & is equally effective. Many car stereos don’t provide an aux audio input though.

@George_San_Jose1 I use cassette tape aux. Didn’t even know technology like that was possible
