If Pioneer's AppRadio (SPH-DA01) ever sees the light of day, it'll join a long list of integrated and aftermarket products trying to play off of the iPhone's success. According to CrunchGear (and its anonymous tipster), the FCC-leaked device boasts a 6.1-inch touchscreen and built-in apps, along with a USB port for accessing content (and presumably, the data connection) on your iOS 4.1 devices. We imagine the hardware to be similar to the 6.1-inch AVIC-X930BT that Pioneer announced at CES, including Bluetooth connectivity, a microSD card slot, and GPS functionality, in addition to an AM/FM radio and single-disc CD player. iPhone connectivity really sets this receiver apart, along with the inclusion of additional apps, such as Pandora and iHeartRadio, with the possibility of adding more apps in the future as well. We're incredibly skeptical about the device's GUI having any basis on the mockup image above, but if graphics are anything like those on the models we saw at CES, we don't expect to be disappointed either.
