I replaced the battery a few days ago and now the radio does not work and asks for a code and the auto windows go down but only go up slow by pressing the up every 3 seconds they go up 1/4 inch each time. Do I have to go to a Mercedes dealer to get this reset. My regular mechanic said he cant do it. I do not have the Mercedes car manuel for this car.
