hey thanks now itīs working in fact, in 3760 there is a hiden folder with the name \.System , inside i've found the maps of USA, Canada and Mexico, for the brazilian version i 've only created in the root the \map folder (as you said) and now itīs working, my remaining question is if the appearence will be like a track source map insead the CN maps, that have better image quality, because what i saw is that the image is like track source? Another one, if i want to have CN Brasil 2011.20 without the TRC maps, how can i do that? Thanks in advance for your feedback
