i looked into this ages ago...i think the reason why its one use only is because it works in kind of a "cut and paste" method...so it takes the settings from the KW100 and puts them onto the car...and i believe it does the opposite if you ever wanted to remove the settings (not sure why you'd do that tho lol)
