If it doesnt, manually switch to USB using the cars source control. Youll be able to play your iPhones audio through the car speakers.

How do you connect your iPhone to your music system?

To connect your iPhone, iPad or iPod to your home stereo you just need a 3.5mm to RCA cable like this cable above. The two RCA connectors plug into the back of your stereo and the 3.5mm plugs into the headphone jack of your iPhone. Pretty much every stereo available has RCA inputs as the standard inputs on the back.

What to do if you dont have an Aux port in your car?

If your car or radio doesnt have an auxiliary input, youll be better off with an FM transmitter. Effectively, the FM transmitter of today is a Bluetooth receiver, but instead of sending the audio to the stereo via an auxiliary cable, it broadcasts it over an open FM radio frequency.
