Just purhased a 2002 STS and the Only thing that doesnt work it seems is the Tilt Door button for the Nav and DVD Access. Since I dont have an Owners Manual yet, i'm not sure exactly if there is a special way to access any program or screen that may enable the Tilt Feature. I'm not quite ready to give it a slight PRY to see if it's just Jammed like some Aftermarket systems get,..and I dont know which way it tilts Anyway. Suggestions???
