THIS The internal memory devices that folder ManualReader I copied igo.exe and the rest of the necessary files and folders (content .....), then I renamed the file ManualReader.exe in ManualReader1.exe a name ManualReader.exe gave igo.exe UNDERSTAND what I did. Right. Then I turned off the navigation. On, immediately started the standard NAVIGON software but now the magic happens. WHEN the initial screen select the BOTTOM OPTION so GUIDE. EEEE now start IGO or PRIMO. In this way navi itself include a GPS receiver and he's doing, and IGO easily detect the GPS settings. Who understands me realize is, it's crazy.
