you can use tomtom bisiness - TTB_ServiceUpdateTool or like to put maps ...but it's important that you also had charge ttevpoinav4_vX.ttpkg inside internal tomtom's memory ..because without ttevpoinav4( cherghing eletric station) your tomtom will not see other Poi or PDI ...SO MUST PUT ttevpoinav4_v30.ttpkg First... many tomtom had ttevpoinav4 inside so no need to put them , but some tomtom haven't them....so must load ttevpoinav4 inside your tomtom
