Pioneer's revolutionary, game-changing AppRadio is the first car stereo to revolutionize the driver's smartphone experience by bringing compatible iPhone 4 apps to your dash. When connected to an iPhone 4 (or a 4th generation iPod touch) loaded with Pioneer's free AppRadio Application, the AppRadio in-dash stereo provides the ultimate in-vehicle smartphone experience. Featuring the first ever in-dash, capacitive touchscreen, you can enjoy full on-screen access and control of your iPhone contacts, calendar, maps, and more with an intuitive interface, formatted and designed specifically for safer in-vehicle operation. Pioneer has teamed up with several app providers to offer compatibility with many of today's most popular in-vehicle apps, while also developing an expanding catalog of AppRadio compatible apps for future features and functions that can be easily and seamlessly added. AppRadio will even notify you when new compatible apps are released.
