Is there a way i can hook up my iphone and listen to music in the car?

But i don't have a cassette player, is there a way to do that without having one?

You need a radio system with BLuttooth or a Case Player.

Cassette Player option - go to walmart and get a $5 mp3 cassette adaptor

Bluetooth Option - SYNC iphone to radio system via Bluetooth. Go to Walmart and get a cheap $50 car radio system, read English, and self install into your call.

If you're stereo has an aux input than you can. Also if your radio is Bluetooth compatible you can also.

You can using the AUX input, it's easy. This may help:
