Although several auto manufacturers have offered vehicles with embedded WiFi connections, Audi is the first to offer a high-speed 4G LTE connection in North America, beating General Motors to the market by a few months.
With the Audi MMI Connect interface, the driver can access Google Maps graphics through the navigation system, keep tabs on the news or weather and update Facebook. In addition, the MMI controller has a circular touchpad built into the top of it that allows for text entry via character recognition.
The IHS teardown team took a look at the inside of the retractable display unit of the MMI system.
