The solution to this problem may require you to (A)remove the panel or (B) unplug power to the panel both which may result in a code to be input??. Stuck buttons are usually a result of sweet drinks eg coke or an overzealous use of armourall on the interior of the car. If it was coke then with the power disconnected use distilled water with q-tips or to help evaporate the water clean up with pure alcohol and leave to dry.Commpressed air also might help. What you are trying to do is to break down the sugar that has gotten into the cracks around the buttons. If it was just armourall then use just the alcohol, but note this will remove the finish on the buttons if your not carefull because they appear to be painted so the white numbers will shine through.The buttons on my radio are worn out on the 1 and 3 positions.If you have any questions e-mail me.
