the key on the side above the joystick is not working as well as it was in the past. I use it a lot as my map keep so it gets used a ton. Now when I press it the map opens but then won't close when I press it a second time, I have to press it a few times to get it to close. It does not seem to be a button I can try and clean under or lift out. No idea how old this is but I assume it is out of warranty
