Hi, I've recently purchased a C220 CDI Coupé and I swear that when I picked up the car I had a clock display on the Audio 20 unit when switched off (also the whole radio remained lit with the headlights on rather than just the on button). This no longer seems to display unfortunately. Does anyone know how to get it back? (Also I have a ViseeO MB-2 fitted, would this have disabled the clock? And does anyone know how to allow the phone to work when the radio is switched off?) Many thanks, Andy.
