Mercedes-Benz has unveiled plans to integrate Apple’s Siri voice assistant into its A-Class vehicles, according to a report from PSFK. The integration would allow drivers to access their iPhone apps using voice commands. The feature is being called the Drive Kit Plus program and will work in conjunction with Mercedes-Benz’ Digital DriveStyle app to translate the iPhone’s screen onto the in-car display. The program will feature compatibility with popular apps such as Twitter and Facebook pre-installed, and drivers will be able to listen to music, change radio stations, update their status on social networks and send text messages using voice commands as well. According to the report, the car’s integrated Garmin navigation system will be also compatible with Siri commands. Mercedes-Benz is the first car maker to integrate Apple’s voice assistant into a vehicle, with the feature reportedly set to debut at the 2012 Geneva auto show next month and a rollout to all A-Class vehicles scheduled to begin this fall.
