1. A method comprising:
presenting, by an operating system executed by a primary device, a single communication interface by which a projection application establishes a first transport between the primary device and a vehicle head unit that facilitates execution of a projection mode in which the projection application projects data for presentation by the vehicle head unit, the data including at least a graphical user interface for presentation by the vehicle head unit;
transmitting, by the projection application and during execution of the projection mode to project the graphical user interface, the data via the first transport;
switching, by the operating system and during execution of the projection mode to project the graphical user interface from the primary device to the vehicle head unit, from the first transport to a second transport; and
transmitting, by the projection application and during execution of the projection mode to project the graphical user interface, the data via the second transport.
