Any help appreciated. The MyLink System on my 2014 Traverse is on a continuous loop where all it does is reboot itself. I turn on the car, the MyLink logo flutters to life, the CD ejector activates and the home screen appears. Three seconds later, it does the same thing again. Over and over. Very good local mechanic had it for five hours today and could not find issue. Have tried every trick found online: Calling Onstar and hanging up, leaving door open for 10 minutes, disconnecting battery. Tried resetting unit to factory settings but it won't stay on long enough to let me get to the Settings screen. Mechanic says he thinks only option is to replace the whole until for $1,000+.
