Power Door Locks Not Working problems of the 2005 Mercedes Benz S500

Electronic dash instrument cluster went black and the speedometer could not be seen and all other driver information on the remaining gauges were also not visible. The door locks would not operate ,the trunk would not open and the seant would not move in any direction. I was driving the 118 freeway in CA . I was doing 65 mph when the incident occured. I had to get off the freeway and drive home on surface streets. Way too dangerous to continue on the freeway. The car has approximately 99000 miles and had no other problems.
