Carletter Cast (com.carletter.mlink) is a specialized screen-mirroring application designed to bridge the gap between your smartphone and a vehicle's infotainment system. It is specifically built for head units that run Carletter software or PhoneLink, allowing you to mirror your phone's entire interface onto the car's display. Core Functionality

Screen Mirroring: Unlike standard Android Auto which provides a simplified, driver-safe interface, Carletter Cast mirrors your entire phone screen. This allows you to use apps not typically supported by Android Auto, such as YouTube or Netflix (though this should only be done while parked for safety).

Hardware Dependency: This app is not a standalone solution. It only works if your car's head unit is already equipped with the Carletter or PhoneLink onboard system.

Connection: Users typically pair their phone via Bluetooth or a hotspot to the head unit, which then launches the mirrored interface as if it were a native application. Installation & Technical Details

Official Source: While it can be found on Google Play, many users seek the Carletter Cast APK for manual installation on aftermarket Android head units.

System Requirements: It generally requires Android 6.0 or later to function correctly. Switching from AutoLink to Carletter
