Griffin Technology has launched the iTrip for the fourth generation nano, designed to fit "seamlessly" with the latest iPod.

Compatible with all generations of nano, but "specifically designed" for the 4G model, the iTrip broadcasts music from your iPod directly to your car's FM stereo, allowing you to listen to your tunes on the road.

The new iTrip for iPod nano 4G includes Griffin's station-scanning feature, SmartScan, that seeks the best open FM frequency then saves it automatically for easy recall later.

The new iTrip sources its power from your iPod so Griffin says there is no need for trailing wires to connect it to another power supply.

iTrip for iPod nano 4G is priced at £29.99 and is available from
