hey guys new to this forum as i just purchased my 2007 s550 a month ago everything has been fine then all of the sudden yesterday my radio and screen display has been shutting off intermittently so i pulled the battery cables loose as i read on another forum off the front and rear batteries and that didnt seem to do anything then all the sudden it came back on a few minutes after i reconnected the batteries ... car drove fine for a day then today it has done the same thing except tried battery cables again and nothing comes on this time at all after several hours of still driving the car and going through multiple key cycles on and off....when i first power on the car i do get a mercedes emblem will flash on the screen for several mintues then goes solid black .. can someone please help thanks
