I use a cassette tape adapter (forget the brand, but bought at Best Buy for $20) that works well. Just plug the jack into the iPad and turn on the car player and hit play on the iPad. I also use my iPod this way. If you don't have a tape player and have an audio input, a simple cable will work. If you don't have that, there are some FM transmitters (expensive and don't always work well), that will do. You can also go to a car audio place and they can install an audio input and connect it to your car radio. That would cost you about $100.
