I have a 7 "of Xtrons that does not leave the selection screen, GPS and manager functions, thus can not access the maps and not the executable. What part of the touch screen which key it accesses the page up buttons and page down and return to the main menu with the functions of radio tv etc.. that are running. Perhaps the resolution in Windows CE 6, but as I mentioned I can not enter the office manager to run Starwin that ran in previous period. Someone went through this, know how to unlock the screen to access functions.
