I have four genuine Apple nano docks for sale. The model number is MA072G/A. These were made for the 1st-generation iPod nanos, and I have no idea if they will work with 2G models. These docks are brand new, and have never been opened. $14 each includes first class shipping in the U.S. Payment must be PayPal. I am a verified PayPal Business member. Please PM me for more info. Thanks.
