GM is introducing a new connectivity feature dubbed IntelliLink in its Buick and GMC line of cars for 2012, which is essentially designed to connect to a driver’s smartphone or other portable device and then control it using the vehicle’s touchscreen display or in some cases through voice activation or steering wheel mounted buttons.

For Buick, IntelliLink is debuting in the 2012 model year Verano, Regal and LaCrosse while for GMC it will feature initially in the Terrain.

The system connects to the portable device using either Bluetooth or USB, so not only smartphone users will benefit. And, it can also enable streaming stereo audio through services like Pandora Internet radio and Stitcher SmartRadio.

Most importantly, IntelliLink enables seamless integration of stowed portable devices with each vehicle’s infotainment system, allowing drivers to keep their hands on the wheel and eyes on the road.

The other advantage is that even without a mobile device, IntelliLink users will benefit from the system’s enhanced voice recognition technology and the included display screen.
