This adaptor means that you can play & control your iPod from your factory fitted car radio. Designed to plug into the factory radio fooling the radio to think it had a CD changer connected. The adaptor will work with virtually any iPod & iPhone that has the standard dock connector on the bottom. Once the iPod is connected you use the radios built in track up & down buttons to make the iPod tracks move up & down. Text display is NOT supported, the radio will just show track consecutive track numbers. The iPod can still be controlled directly if needed.
