Actually the Operators Manual talks through Text Messages and the GMC Marketing info also has it. I have placed a call into the Intellilink Support team and they are reviewing. Really would like to know when Text and the Upgraded App Shop will be available to us early buyers???

Hopefully a GM Customer Support rep will see this thread and chime in. Like I explained to Chris in the other thread I shouldn't have to use an external supplier to provide functionality like this. I've had multiple other brands of vehicles with much lower price points that this feature was included or available.
If the link above doesn't work here's what I was referencing:
The 2015 GMC Yukon’s next-generation IntelliLink infotainment system is better connected and offers passengers more choices for their increasingly plugged-in lifestyles. It provides easy, intuitive operation of basic functions, yet it is also highly customizable and capable of linking up to 10 devices such as smartphones, SD cards and MP3 players, giving customers more ways of staying connected.
Enhanced connectivity and convenience includes a new Text-to-Voice feature for smartphone users with Bluetooth profile (M.A.P.), which reads incoming texts through the vehicle’s speakers, and Siri Eyes Free for iPhone iOS 6 and iOS 7 users to enhance connectivity and convenience. Each enables voice-controlled connectivity, to help keep phones in pockets and hands on the wheel.
Additional standard and available features include:
■Eight-inch-diagonal color touch screen and multiple USB ports
■OnStar 4G LTE with built-in Wi-Fi hotspot (later availability)
■Next-generation OnStar and IntelliLink enhancements with gesture recognition and natural language voice recognition
■Available GMC AppShop (later availability)
■Available navigation.
With OnStar’s 4G LTE connection, each Yukon becomes a mobile hub for drivers and passengers, providing easier access to apps and services that require a high-speed data connection. The vehicle employs an “always on” wireless connection, which is not reliant on a brought-in mobile device. The OnStar 4G LTE connection arrives later in the model year.
A mid-model-year update will also bring 2015 Yukon models a new in-car app marketplace: GMC AppShop. It allows customers to download apps directly to their IntelliLink system and organize, update or delete them. Available apps will connect drivers to music, news, weather, travel information, vehicle data and more. The initial list of apps includes iHeartRadio, Priceline.com, the Weather Channel, NPR, Slacker Radio, TuneIn Radio, Cityseeker, Eventseeker, Glympse and Kaliki.
