If you really want to get fancy, you can install a new head unit on your vehicle like this one:

I'm planning on installing one of these in my vehicle actually. It is a nice modern addition you can install in your car. One of these is the best option if you want something nice looking with blue tooth, music, and GPS functions. In some older vehicles you will need to splice a different connector in place of the old connector in order for it to work.
Edit: Someone already beat me to talking about a similar thing, but that's because it is a good idea
