My little girl rides in my car a lot (thanks Wendy Filters) but as she gets older she’ll figure out how to change the filter when I’m not looking and because some dim bulbs at work locked-up my player the other day messin’ with it (growl). Since I'm not a programmer how hard would it be to set up “parental controls” on filters and maybe other settings but the filters are the only settings I would like to see have a “parental control” option on it.
