I bought this car used and to my dismay the radio didn't work. Upon further searching i found that the entire 6-CD changer that comes with the car was missing, and the wire connections were unplugged. I was wondering if this is the reason why the radio is not working. The actual radio is still there but doesn't display anything (except for the time when the engine is off and i press the button to change the minute or hour. Anything you have to offer would be greatly appreciated

And the radio also includes a digital climate control.
