What's the 2004 Nissan Quest aux input location?

The 2004 Nissan Quest does not come with an AUX port for the Audio for the stereo. This is a bit before the time where auxiliary ports became common and therefore it does not come with one from the factory. If You want to add an AUX port there are ways that it can be done. There are third party cables that can attach to the back of Your stock head unit to allow You to connect devices to the vehicle. You could also change out the head unit in Your van and put in a new one that has AUxAnd USB functionality to add more ways to play music in Your car.
