You spend a lot of time in your car. It allows you to commute to work, run errands and go on long road trips. Your car is more than a vehicle that gets you from one place to another. It's like a second home. It's important to be safe, comfortable, entertained and connected. While a factory-installed car radio provides some entertainment features, it generally lacks the audio quality, safe hands-free calling features and smartphone integration of after-market car stereo systems. The best car stereos provide high-quality audio with many playback options while maintaining a hands-free connection to your phone.
