Honda has already announced the 2014 Civic which will be the first Honda to integrate Apple's system, and Siri Eyes Free is planned to expand to more 2014 models. The interesting part is that it is planned to be a full in-car mirroring system, and not just voice command. The full story on the new features is planned for the first week of December, but we already know that the Civic will feature a 7-inch multitouch display.
We're quite interested to see exactly what this "mirroring system" could entail. Apple is already working with Audi, BMW, Chrysler, General Motors, Jaguar, Land Rover, Mercedes-Benz, and Toyota on expanding the integration of Siri.
