Cosmos ® Black Cable 3 Ft USB Charge and Sync Data Cable + Dock Connector Extender Extension Cable for Ipod Touch Iphone 4 4s 3 3Gs + Cosmos Cable Tie
This cable extends the iPhone docking cable built into the glove box of my 2010 Mercedes Benz E350.  It is a great way to allow me to keep the iPhone 4s outside of the glovebox and use it while I am in the car.  Good price, good product.
