Good morning, My great joy in my new DS4 has been quite clouded since last night… And that’s when the navigator or the entire system, including all the music functions and parking beepers, doesn’t wake up anymore. Every few seconds the Citroen logo flashes up in the display, the CD drive turns up for a short time and then there’s nothing again. Pressing all the buttons, restarting the engine, letting it stand overnight didn’t bring anything. My garage said I had to pass the car. and leave it there all day long (!) great. And that after a proud 2500km… Did someone experience something similar or even know a solution? Is there any way in which I can perform a hard reset using a button combination at best? Thanks and Greetings
