Pioneer App Radio officially unveiled

Pioneer has officially unveiled the App Radio that AutoWeek told you about earlier this month. Now that it's willing to talk, Pioneer claims that the radio and audio system is "the first in-vehicle product designed to utilize the processing power, storage capacity, network connectivity and apps of the iPhone and iPod Touch as the primary source for its information and entertainment capabilities."

Pioneer said it couldn't speak to the similarity of those systems, but Ted Cardenas, director of marketing for Pioneer's car-electronics division, briefed us on installation of the device and what Pioneer is doing to minimize driver distraction.

These include the angular, flat C-pillars and the rectangular headlamps and rear lamps.
