AirDock - Charging Dock with Remote and the difference is remote control.
AirDock
It's a place to put your iPod. A place to recharge its battery. A place to sync with your computer. A place to plug in your iPod while you enjoy its music.
Connect AirDock to your computer's USB port. Plug in your iPod to recharge its battery while you sync with iTunes.
Connect AirDock to your TV or stereo using the included Griffin HomeConnect cable. Sit back and enjoy your music, photos and videos, and stay in control using AirDock's full-function RF remote control - it even works through walls.
Everything you need is right in the package, including the very best AC adapter we could find: Griffin's own PowerBlock.
