Once connected, an iDevice's Maps app, for example, would override a car's included and proprietary GPS navigation with its own. The version displayed in-car would be optimized for the center console's built-in display.
The sources -- and there were multiple sources reporting the same thing -- described the functionality as basically mirroring the display of the iPhone’s Maps app onto the bigger screen included in the vehicle's console. This functionality would differ from the new Volkswagen iBeetle that uses a VW app which integrates an iPhone with other car services.
Apple could debut this new in-car integration at WWDC in June, or at the (expected) later iPhone hardware event this year, as the feature would seem to be iPhone-specific (no one -- we assume -- would want to mount their iPad on their dashboard). It's unclear when the Cupertino, Calif.-based company will make such a move.
An announcement doesn't necessary mean quick delivery, either. At WWDC 2012 (last June), Apple announced that Audi, BMW, Chrysler, Honda, General Motors, Jaguar, Land Rover, Mercedes and Toyota were all on board for its Siri Eyes Free program. To date, though, only General Motors has implemented the feature -- and only on two Chevrolet models. Of the rest, only Honda and Mercedes have announced actual plans.
A natural question about this feature: Do you really want Apple's Maps app giving you directions in your car, considering the numerous stories of its mistakes, some dangerous?
