I got a new conversion van a couple of weeks ago. Today a friend and I were trying to figuare out what a button does. We decided to take some stuff apart to see if we could figuare it out. In the process we decided to remove a small plastic rectangle expecting there to just be a hole on the otherside. Instead we found 3 buttons, I pushed one of them and a whole bunch of lights lit up. It was a hidden cop detector. Rock On!!!!
