My brother handed me down his car and the radio in it doesn't have a USB port, but it does have a wire coming out of the back for an iPod or iPhone. Now I do have an iPod. But I like to listen to pandora a lot. I bought a female iphone to a male 3.5 mm headphone thinking this would work. Well I got it in the mail today and it doesn't work. Is there anything else I can do? Any apps maybe? Please help
