Sorry guys trying to get a picture on the site. Theses buttons are found between the speakers and the edge of the windjammer.
saw your picture -- that switch with the blue light is not stock. I can guess what it controls but I don't know. Maybe an audio amplifier?
Also there is no storage box under the interstate seat unless you are talking about the extra little bit of space next to the battery -- I used that sapce to put my CB radio in but that is about all it will hold.
You can get the seat off by using the key in the key hole on the left side of the bike. it is in front of the side cover that covers the coolant overflow storage but it is under the tank -- hard to see at first but it faces forward of the bike -- just look in the opening under the tank on the left side.
