Navigation panel issue

[pjcag]

Our navigation panel went black last night so radio etc nothing works. I saw a post where others have had same issue and said to do a reset...we can't find a reset button? Saw one post that said its by the eject button on CD but we don't have a CD..thanks

Off to the right of the buttons under the Nav Screen and vents. Right next to a round knob reading "enter, tune, file". There is a small hole just to right of knob. Use a paperclip or similiar and press into the hole. The hidden button is there
