yep. I purchased mine from
www.crutchfield.com but they are sold all over the internet and you can actually buy them and have them installed at best buy if you don't feel comfortable doing it yourself. It does cost more than an FM transmitter, but for me it's well worth it. I listen to music non-stop in my car and I drive a lot. This got rid of a HUGE stack of CDs for me with much better quality than an FM transmitter. Not to mention FM transmitters don't work in large cities and also this charges your iPhone once it's plugged in, whether you're playing music or not.
