Ford has conducted its first major on-the-fly update of its Sync software. The update, which is being offered to more than five million vehicles equipped with the company's infotainment services, can be applied to any Ford vehicle from model year 2011 forward that has the second-generation of Sync.

The update notably includes Siri integration, with access to Siri's hands-free help gained by a long press of the voice recognition button on the steering wheel.

The software update is available for the second-generation of Ford's SYNC, commonly called MyFord Touch in North America. SYNC was engineered from the beginning, Ford says, to be capable of receiving updates without going to a dealership. The third-generation of SYNC, already includes Siri Eyes-Free and has begun appearing in vehicles for the current model year.
