OK, now for real. It is rather expensive, but possible. You need a notebook in order to get good speed on streaming. And a pc-card, wireless connection. Only you need one that uses the cell phone network. Get a subscibtion, and hook up the notebook in your car with a car adapter. Than get a radio with a aux input, and connect it to your notebook. Or get a FM modulator and hook it up to your notebook. Tune in on the frequency with your car radio. Problem solved. A other thing is with a cell phone. but than you are continiously online. Each way it is rather expensive. Good luck!
