Hi everyone.Traded in my old DS4 D-Style yesterday and drove off in a new DS4 Prestige. This morning when I got to work the reversing camera appeared to have failed (it worked when I reversed off the driveway), but closer inspection showed the screen had frozen as the time was 45 minutes out, and the radio wouldn't turn off when the engine was turned off. Eventually it turned off. Restarted the car later and everything appears to be ok - for now !!. I see the DS5 forum reports similar issues. Anyone else had similar on a DS4. Great start after 30 miles of ownership !
