I don't have the GPS navigation package - just the big stereo and A/C display. It's completely invisible now. All the other dash and interior lights work fine. The stereo itself does work and so does the A/C system although it's pretty hard to blindly adjust either. The dashboard dimmer operates as usual, except that the radio backlight is totally dark. This is baffling - I don't think there's a separate fuse for the backlight since it draws so little power. Casey
