This item is used, but works fine. Sold my old iPod so I have no use for this now. It works with compatible iPod models (see below). This uses the older dock connector, not lighting. Comes in original packaging!

The Griffin Technology 9500-TRIPDA iTrip LCD/FM Transmitter with Dock Connector for iPod is the most popular iPod FM transmitter in the world. It lets you avoid the hassle of bad reception and bad music on your car's radio by transmitting your iPod's music directly to your FM radio. The iTrip has a large, easy to read backlit LCD screen, memory settings, and a snazzy compact and self-contained design that's great for car travel. iTrip even has international modes for when you're in Europe or Japan and are looking for a frequency below what's available in the U.S. mode. Meanwhile, the new option of selecting between LX and DX modes allows you to hear audio with minimal interference from stations on crowded urban dials.
