How to listen to my iPhone 5 in the car?

I have just got an iPhone 5 and would like listen to music/audiobooks from my iPhone through my car stereo. I used to use an iTrip with my old 3GS but it doesn't have the same connector. People have said that the new converters only help with battery charge and not music, so what other methods could I use to listen to my iPhone in my car?

PS I could stick to headphones, but I'm not a fan of that option

Just get an fm transmitter

Depends what sort of stereo system you have. If it has a headphone or USB port you can get cords for that.

If your car's radio has a headphone port you could get a dual sided headphone cable & plug it in & play it through the auxiliary section
