Thank you, I know you're trying to help, but if I could get the button to push I wouldn't have to post this. It does go automatically to the navigation but I can't stop it from going there because it won't let me push any button on the screen. I tried an update from my jump drive and it recognized it but I couldn't push the button to even say "yes" to accept it. I got an idea to use the remote and I can select the warnings button and it goes to the map but when i go to the calibrations page it just goes to the brightness screen and I cannot move to the calibration part with remote and touching screen still does nothing. I tried updating and the blue bar goes half way across and stops. Half hour later no change. Deleted package and tried again. It goes a third of the way across and freezes. What is wrong with this thing?
