Has anybody had this problem? It has happened a few times with me. I turn the car on and everything boots up as normal but the main infotainment screen fails to light up. It has also suddenly switched off whilst driving a couple of times. This worries me, if I was using the sat nav then that could cause problems. On one occasion I drove to my dealer when it failed to light up and showed them. They took it into the workshop and, as you would guess, it turned on just as it went in. They checked all the connections but could do little else. It has happened a couple of times since then. The heater and AC still work but you cant see the settings on screen. The radio will not work. Anybody else had this??
