I work outside the office. Several years ago my company gave us TomToms. Well they loaded a bunch of stuff in them, client addresses and such. I used mine once, then it shorted out. Apparently there were password protected menus within the unit that become visible after the unit shorted and the unit went back to default. I found a locator function, a function where they could track my movement without my knowledge. The unit is now a paperweight in my home office.
