Good morning. I have a stereo 8100 NEX, which comes with maps of the United States and Canada. Toolbox doesn't give me the option to buy other maps, because the stereo appear not to accept other maps. I already got some maps of South America (iGO), but I don't know how to install them. Can someone please help me? Or does anyone know how to display the list of files, including executables, from the SD in the stereo? Thank you!
