What T F, over
Few questions for the style I have in pic below.. (or was it 88-94 maybe..)
The buttons, are they supposed to be lit up, lights on? The lettering and symbols? Mine aren't.. :dunno:
And the fluorescent display, is there a way to dim this thing when the lights are OFF? It's annoyingly bright when no other lights are on engine running or key on..
