I got this radio six years ago from 1 Factory Radio for my 2004 Ford E150 van. I drive long distances, and oftentimes out of reach of suitable radio stations. The auxiliary port provides the answer when I connect it to my iPad with cellular signal, and be able to pull in distance stations through Apple apps. I can get all the news, country western, jazz, classical stations from around the world. I can also access endless selections from YouTube and other sources. Being able to seamlessly connect an iPad (with cellular) to such a very dated radio brings all the luxury sounds of a modern vehicle radio.
