Yamaha YIDW10 Wireless Dock System in Black uses the Yamaha "y Aired" technology to establish a wireless connection with another Yamaha dock-compatible component. Yamaha YID-W10 means that you can enjoy iPod/iPhone audio through the A/V receiver while viewing cover art, watching videos or playing games on your iPod/iPhone screen.
