If the buttons really bug you that bad then get a set off of a '00 model. You should be able to get them from a dealer. The only thing is since the buttons are the same shape just different lighting I don't know if Nissan would have stopped making the old ones and only make the new style now. If thats the case then you should be able to find some off of one in a junkyard. The ones from the Frontiers are the same too.
