I try update maps on a Go 720.
I make a copy of the content of the gps.
I run TomTom Home and was a update of the application for the tomtom available, well i click on update, thinking that i after of that i will patch the navcore for accept the new map.
after patch the new navcore -that was the same that the old one, 9.205- , was impossible that the gps recognize the new map!
I download 4 maps thinking that the new application was incompatible with the maps, donīt work.
I update meta, Fastactivate etc.. no luck.
Luckly i have the gps backup, i copy on the internal memory , patch the map, and all work fine.
