So yesterday I turn my 2012 Terrain on after a stop at the hardware store and the radio screen is blank, no sound, none of the radio buttons worked. The HVAC controls still worked. I turned the car off then on again twice and still nothing. Pulled & checked the various fuses related to the radio. Then I got in through the driver door and the GMC logo came across the screen and shut off half way through the GMC animation. Once I started the car the radio was fine again. Has anyone else experienced this?
