I purchase the Garman nuvus 1300 and plan to return it after a few day of use : issue be 1 . touch screen be not very sensitive - require a hard push along with extact placement or do not register the touch . 2 . pop-up - unbelievable - ad pop-up for hotel , commercial business etc. . block about 10 % of the screen - no instruction in manual , or set-up munu to toggle off the annoying ad - ad stay on screen until you leave the vicinity of the business - very distracting . I be go to a different brand .
