Many newer cars come with some pretty cool features — navigation, smartphone access, and even touchscreen control. But if you've got an older ride, Pioneer's figured out a great way to add many of these advantages with a single-DIN CD receiver. Pioneer's DEH-S4220BT CD receiver is a cool fusion of car stereo and smartphone that features Pioneer's Smart Sync app. It brings your nav apps, messages, music, and more together with a well-designed interface that stretches the limits of what's possible in your car.
