IPhone 4 play music through stereo?

What is the name of the cord that you use to plug in the headphone jack of a iPhone to play music through my home stereo?

Auxiliary cord

Auxiliary cord. It looks the same as a regular headphone jack but instead of head phones on the other end both ends are the jack. There's also a coaxial cord which I know nothing about but that might be it.

  • Would this stereo car deck allow me to play music from my iPhone 5 in high quality? I don't want to use CDs anymore and my current car deck doesn't have USB functionality. I want to play music without using the transmitters that usually have bad quality. Would this do the trick: http://m.futureshop.ca/defaultpage.aspx?lang=en#/catalog/productdetails.aspx?ajax=true&sku=10220448&lang=en-CA I'm open to other product suggestions as well. Willing to spend in the hundreds.

  • What is the device called that connects your iphone to your car stereo to play music?

I just got an iphone and i'm iphone-illiterate.
