If you want to listen to Internet radio while driving but there isn't exactly room in your budget for a new car, The New York Times has some suggestions.
The first is the Livio Radio Car Kit (pictured), which streams web radio from your mobile device (via Bluetooth) to your car stereo (through an empty FM frequency). You can read more about Livio's Car Kit in RAIN here.
The New York Times also highlights Pioneer's AppRadio. The device features a 6.1-inch touchscreen, which drivers can use to control Pandora and Rdio playback. Engadget recently review the AppRadio (here).
