In city of Athens for example Tomtom its beter in numbers for some central roads like Sygrou avenue,some streets in Melissia, streets in East Atiki,Marathonas, Gramatiko,Ag.Stefanos.You an find the inside streets of Hospital Sotiria in Tomtom,the differences is very small and and from the year 2012 the maps is much better than early years
