Have bought a second hand GPS 60c and tried to use it with my own registered copy of mapsource that I had on a Street pilot 111 and it is not unlocking the maps for me. Message also comes up on the unit that "cannot unlock maps" I have also tried to register it with garmin but of course it comes up as an already regsitered unit so stuck as to what to do next. Any advice please.
