Zlink is a pre-installed application commonly found on Android-based car head units, particularly those manufactured by companies like Eonon, XTRONS, and other generic Android radio systems. Unlike built-in systems such as Apple CarPlay or Android Auto, which require specific hardware licensing from automakers, Zlink acts as a bridge. It allows a head unit running Android to communicate with a smartphone via three primary protocols: Apple CarPlay (for iPhones), Android Auto (for Android phones), and MirrorLink. This makes it an economical and versatile solution for aftermarket radios. zlink 3.9.27
