Hi all I have recently bought a 2015 S80, and the screen goes blank, radio not working etc... did not work sat for a journey of 70 miles, next morning did, then today worked am and not for return journey where this after noon a thin bar at bottom did decide to show fan speed and temp for heating controls but nothing else working...
