ok, really thank you for all the help, one last question, whenever i download a map there are always two jcv files one larger and one smaller... doesnt it mean that the smaller one its split screen? whats the differences between those two files?
what do people with newer models with split screen jv and want to download maps for north america or europe and dont want to lose the jv function? paying is the only way? lol
Also will the lane assist come merged with the map.img? or is there a separate file for that?

thank you very much!!
