I just got TV nav installed (Farenheight wide screen) with TV tuner. For some reason everything is working fine, but the stock radio (non-bose) now does not light up when I turn on the lights.

The area where the clock is back lit, but none of the buttons are lit which makes it very difficult to see which buttons to press to change stations or CD, etc.

Any clue on this wiring mishap? We thought we forgot to connect a wire, but after taking it apart it seems to be all connected.
