Just noticed this the other day; the car cannot tell you the time unless you put the ignition on, is that right? Sure, you can switch on the audio without the key in but unless you put it in and turn it to the Acc position it actively refuses to show the time on the main display. Even a 1978 Escort GL could display the time without having the key in! Is this a C-Class peculiarity or are all modern Mercedes the same? Or am I simply doing something wrong?
