The voice control system in our 2018 CLA has stopped working. This happened once before about 15 months ago and I was able to find a place in the menus to turn it back on. Unfortunately I don't remebe how I did it, and I have spent over an hour going through the menus in the car without finding. Searching the operator;s manual and the COMAND manual were no help. If anyone know how the help would be appreciated.
