SYNC AppLink

SYNC AppLink are APIs that provide the ability for developers to extend the command and control of a mobile application to the vehicle.

AppLink is a suite of APIs that provide the ability for mobile developers to extend the command and control of a mobile application to the in-vehicle Human Machine Interface (HMI). AppLink transfers the normal functionality processed by touching a mobile device screen in to the familiar vehicle controls such as voice commands, steering wheel and radio buttons, and capacitive touch screens. The applications run entirely on the mobile device without the need to install any software from the apps in the vehicle head unit. The AppLink APIs exchange program data as well as command and control information over a known transport layer allowing the SYNC system to exchange messages with any AppLink enabled application in a predetermined format. This template approach removes the burden from developers of having to recreate any UI on the vehicle display. This technology is similar to how Bluetooth devices and digital media are integrated to work on various production platforms. SYNC is an integrated in-vehicle communications and entertainment system embedded in Ford and Lincoln vehicles. SYNC handles all of the commands sent from an AppLink application and delivers the intended message inside the vehicle. All UI including commands, display requests, vehicle data authorization, and responses are managed by the SYNC system on behalf of the mobile application, and communicated over AppLink.
