Pioneer showed its hand following earlier leaks and unveiled the AppRadio on Wednesday. The in-car system centers on a hinted-at 6.1-inch capacitive touchscreen as its interface, the first of its kind in a car, but is now known to lean almost exclusively on iOS apps for its real strength. Both an official AppRadio app and third-party apps with the relevant code can share the Internet connection, pipe music or video, or navigate the car using Google Maps.
