This started with the icons on the second page, i.e. "Navigate To">then nothing on the next page, e.g. "Favorites" would not respond and eventually shut the TomTom down. Reset didn't work and "Home" update hasn't rectified the situation. I have backed up the maps but one of my chidren removed my backup, thinking it was an out of date version of my Tomato router firmware. What next? Thank you!
