Yesterday, I was driving and out of the blue the intellilink screen went black. I touched the power button and it came back on. Today(Sept. 17th), after returning from inside the mall, I started the vehicle and the screen was black. The radio would not come on. Turned the engine off and restarted the engine and the screen was still black. I drove to the dealer(about 10 miles) and the screen was still black. The service person phoned the radio service people and they have a radio. I will take it in on Thursday. I went out and started the car and radio was working. Shut the engine off and restarted the engine, and the radio is working. Is this a feature of this radio or is there something wrong with these radios. Software update???
