I have updated my GO5000 to the latest firmware but now it will hang and does not work: I can enter the menu (very breefly) and then it hangs (is slow to react one time then it hang) and can not reset to factory default and re-install. What can I do?

The system was working OK but now it is un usuable. How to fix it (I re installed cards voices removed etc etc. but I can not detele the software /system and can not install old firmware...) I really start to doubt TomTom quality now...
