I'm having the same issue as jhecht4942. I can setup the time in the screen behind the steering wheel but not on the smart media system. The "Set Time" option is grayed out.
Got it the last day of May. So far just a little over 1000 miles as I work half of my time from home. I miss some features of my 451 but I'm happy with the 453.Arturo, when did you get the electric smart?
