redletterdave writes "Mercedes-Benz unveiled plans on Monday to use Siri, Apple's AI personal assistant exclusive to the iPhone 4S, to power its electronics system called 'Drive Kit Plus,' which will essentially let drivers access their iPhone apps while driving using voice commands. With Siri, Mercedes drivers will have a hands-free solution to listen to music, change channels on the radio, send texts, or make calls. 'Drive Kit Plus' will also come pre-installed with a number of social networks, so drivers will even be able to update their Twitter accounts and post messages to Facebook. Siri will also be integrated with Garmin's GPS system, so drivers can navigate and get directions with simple voice commands. With this move, Mercedes-Benz earns the distinction of being the first carmaker to integrate Apple technology into its vehicles' in-car systems."
