HOPE THIS HELPS some of the citys in the uk , are going over to , a system called , narvision 3 , and there is no box out there that can read this "system , its has being running here in Ireland for over a year now, and no box will work here anymore , but not all citys in the uk are on it yet, but will be by mid summer . so you might just need codes , if narvision 3 has not come to your town yet . but it will..
