When diagnosing any infotainment system conditions, including blank displays, flashing displays, error or update failed messages, the navigation map not loading, Bluetooth concerns or USB concerns, on some 2013-2015 ATS, CTS, SRX, and XTS models equipped with CUE infotainment systems; 2014-2015 Regal, LaCrosse, Canyon, Sierra, and Yukon models equipped with IntelliLink infotainment systems; and 2014-2015 Colorado, Corvette, Impala, Silverado, Suburban, and Tahoe models equipped with MyLink infotainment systems, check and remove any devices plugged into the USB ports, SD card slots, or 12-volt accessory ports. (Fig. 13)

Any aftermarket equipment should be unplugged prior to diagnosing any infotainment conditions. SD cards that mount almost flush to the slot may be difficult to see.

Many vehicles also have a USB port that can only be accessed by raising or lowering the radio display/control assembly.  Verify that there are no devices in the storage bins behind the display/control assemblies, if applicable.
