I was thinking more for voice control of the phone for making and receiving calls while driving. The access and control of stored music or MP3 player on the phone through the head unit would be nice too.
I wouldn’t want this to have access to essential car controls or operations. There are other ways of doing data logging and telemetry recording if needed by a user.
Smart device link is an open source platform.
SDL is the industry standard for open source in-vehicle connectivity. For automakers and suppliers, SDL adoption broadens the choices for customers in how they connect and control their smartphones while on the move. SDL is the open source software on which the Ford AppLink platform is built. Industry adoption of SDL provides significant benefits to developers interested in connecting their apps for safer in-vehicle use.

As I said this depends on apps and the infotainment system being used. If there is no hardware and is level support it will not function either.
I’m not looking for Android Auto or Apple CarPlay styles of systems. Press the call button on the steering wheel or head unit and say “call john doe” or change tracks in my play list with the up and down buttons.
Hope this isn’t too long and it is clear.
Just as a bit of extra information the Clarion FX688A head unit is SDL compatible.
