Internet car radio

From MIT Technology Review:

Internet radio lets listeners find or create stations that play just the music they like. A dashboard stereo from miRoamer and Blaupunkt brings that kind of control into the car. The stereo connects wirelessly, via Bluetooth, to the driver's phone, which streams music over the cell network. Users can preprogram their favorite stations and create song playlists online. The system has a built-in microphone, so that users can make and receive phone calls by pressing a button on the radio. Cost=$300-400.
