As far as I know, I have just about every option Nissan was able to load onto my Armada, but I still have two blank switches: one to the left of the steering wheel, next to the instrument brightness control, and one on the console to the right of the power outlet - next to the tow mode switch. Neither is listed in the owners manual. Anyone know what they are? ....found answer 7/30...blank switch on console is Titan "lock axle", switch on dash is Tital "cargo light." not used on Armada.
