This adapter plugs into the female 3.5mm (1/8") stereo mini-jack of your car radio on one end and directly into the proprietary Apple connector on the bottom of your iPod on the other. Only officially licensed Apple connectors are used, unlike cheap knock-off products that don't always provide a clean signal.
The cable is coiled so you don't have a big bundle of wire in your car, yet it stretches to approximately 3 feet, if needed. This allows for a multitude of convenient mounting locations for your iPod.
This product is brand new and comes with a 6 month warranty.
