This week, GM rolled out the IntelliLink system. The system connects wirelessy to your smartphone and provides voice-activated access to phone and audio functions. It's the latest example of the growing number of in-vehicle smartphone connectivity systems.

The IntelliLink system turns the vehicle infotainment display into a smartphone-like interface with a configurable series of icons. The system integrates a voice control function that allows drivers to place a phone call and request a specific artist or song without pulling their hands or eyes from their respective driving duties.

In terms of music, IntelliLink offers several options. Drivers don't need a proper MP3 player to enjoy digital music and can simply plug a music-loaded flash drive into the USB port in the center console. The system also allows for wireless Bluetooth streaming from services like Stitcher and Pandora when paired with a smartphone. It displays album and artist information streamed from the Gracenote database on the seven-inch color display.

"Gracenote is typically limited to devices plugged in to the USB port," said GM lead engineer Tony Kraatz. "With IntelliLink, we are the first company to run Bluetooth streaming audio through the Gracenote database to display album art for music players connected wirelessly."

Unlike some other systems available on cars today, the IntelLink system does not include any type of voice-activated text messaging or social networking features.

A public relations rep for GM told us that the IntelLink system will be shared between GMC and Buick. It will be standard equipment on all Buick sedans and will be offered as an option on the GMC Terrain and Acadia. Chevy offers the MyLink, which is based on the same technology as the IntelLink system, while Cadillac has its own independent connectivity system called CUE.
