I have a 2009 smart Cabriolet with a model 10 radio with silver trim.
When the parking or headlights are turned on, the radio on button is illuminated. Picture below
When the parking or headlights are turned on and the radio is turned on, all the radio buttons illuminated.
I hope this helps.

Actually, the volume knob is also illuminated when the parking / headlights are turned on and the radio is turned on. Not when the radio is off.
Mine is covered with velcro fuzz. That is where I put my GPS
