cityXplorer maps are just ordinary City Navigator NT map tiles and in most cases there's also the extra MMR data for Enhanced Pedestrian Mode (EPM). The EPM routing engine is just in some premium nüvi models and all other Garmin GPS units see these CX maps just as ordinary CN maps.

MapSource can't use any MMR sub data for EPM routing and the CN part is from the City Navigator NT release. In this case it's Paris parts from City Navigator Europe NT 2010.10.
Better use the latest [Only registered and activated users can see links. ] with full MapSource install and choose the Paris area in MapSource.
