Scosche tuneFREQ RDS
Plug this sleek, compact device into your iPhone or iPod, and you’ll barely notice it. Solid build adds to the experience as it routes firmly into an Apple 30-pin socket. It claims to show song names on a radio’s RDS display, although this didn’t work for us. No power cable is included, as it runs off your device, but while it performed well, it’s pricey.
