Is the display completely blank?

Do your warning chimes and turn signal clicker work?

 

John is asking if the radio display is completely dark (or not). And when you use your turn signals, or leave the door open with key in the ignition, do you hear the turn signal sound or get door warning chimes? (The sounds are generated by the radio, so this is a further symptom check.)

 

How come again ??

 

I do not understand this question.
