I want to play music in my car but I don't have a place to plug a USB cord in?

I have a IPhone and I want to music off my phone though the speakers but there's no USB port is there any other way I could plug my phone in to play the music?

You can use a 3.5mm audio jack if your radio supports one.

You can also use an 3.5mm audio jack to casket tape converter, I see plenty of those at Wal-Mart clearance sales.

The final way you can do it is to get an FM transmitter.

Does your car have an auxiliary port? If so, you can just buy an auxiliary cable and plug it into your iPhone.

Use Aux port (recommended on every car)
