BMW announced this week that 2014 models equipped with its iDrive 4.2 interface will include Siri Hands Free mode, making it possible to pair an iPhone with your car and use Siri without ever taking your hands off the wheel.
iDrive already includes voice commands, but by pressing and holding the steering wheel-mounted voice command button, you can use Siri instead.
Apple isn't the only one to receive iDrive integration, either - BMW notes that Samsung's SVoice control is also supported.
BMW also notes support in 2014 models for iPod Accessory Protocol (iAP). As a result, users won't need a USB connection to their iPhone or iPod to browse and select music using the BMW controller - it'll work over Bluetooth as well.
