After hooking everything back up last night, I was disappointed. The entire display was very dim as well as the buttons. It was difficult to tell that the buttons were even on, but they were. If I turned on the heated mirrors or central lock, the display "dot" light up well, but the rest was not good. Perhaps you used these?
