Upgrade the stock 4.2-inch screen to an 8-inch touchscreen with navigation for Sierra & Yukon.
This system keeps ALL of the factory electronics (the radio, CD Player, OnStar, Bluetooth, etc.) and changes the small screen into an 8-inch touch screen with built in navigation. It keeps the factory look and feel, too. If the vehicle does not have a back up camera, this system is ready for it! This is for use on the 2014-2015 Sierra and 2015 Yukon. This system comes standard with a Three Year / 36,000 mile warranty.
