Here bellow the installed maps
the original map: CN Europe NTU 2013.41 Southern Europe as Nuvi 2567\.System\gmapprom.img
the added maps: City Navigator Israel NT 2015.10 as Nuvi 2567\Map\CP 1252 gmapprom.img
and and City Navigator North America NT 2014.40 as SD\Map\NorhAmerica.img

So, As I've these 3 maps installed, do I need to make a hard reset? If so, how to make it on my device?
Regards
