What to use to play music in my truck?

I have an iphone 4s on which all of my music is played. I just got a f150 2007 and it doesn't have an auxiliary cord plug in area. Is there anyway i can connect my phone to my car radio to play music? Please answer as soon as possible.

Added (1). I'm looking more along the lines of is there like a auxiliary cord that connects to the cigarette outlet or something like that?

Go to your car audio place and by a bluetooth transmeter and you can use your phones bluetooth to conect to it to use your music thro your radio

You need a Ford f150 auxiliary input interface, this is not universal is made for your vehicle because you have the aux button on the radio that now shows no aux when you press the button
the radio is ready for if this link is to the interface
