How do you get the headphone jack to work in a Honda Odyssey?

To get the headphone jack to work in a Honda Odyssey, first ensure that your audio source (like a phone or MP3 player) is properly connected to the jack. Then, select the appropriate audio input mode on the vehicle's infotainment system, usually by pressing the "Media" or "Aux" button. If you still don't hear any sound, check the volume settings on both the car and the device. If issues persist, inspect the headphone jack for dirt or damage, as these can affect connectivity.
