The Sony XSP-N1BT Smartphone Cradle Receiver ($250) is the first system that turns your mobile device into the interface for your infotainment. Its unique clamping system grips your phone in landscape orientation, and when combined with their AppRemote for iOS and Android devices, functions as the complete input for your stereo. Wireless connection is available for Android devices, while iPhones will still have to connect over USB, which also charges your device while it’s in use.
