Belkin Car Adapters
The Belkin auto adapter not only keeps the iPod's battery fully juiced through the docking port but also offers a line-out jack for connection to your car stereo for a cleaner hookup than you can get with the wireless iTrip. Use the white Belkin cassette adapter (or any other brand) to help the iPod interface with the car stereo. You'll be up and running in no time. Note: You can't use the iTrip with the Belkin auto adapter's line-out.
