Sat-Nav security

Satellite navigation devices, like TomTom, give you the option to set your home address in the device for easy destination selection. However if your device gets stolen then the thief knows where you live and if you're unlucky enough to have your keys stolen as well, you're in trouble! So, when you set the home destination, put in the details for the next street or perhaps a landmark in your street to keep your own address secret.
