When you program "Home" into your GPS, don't use your real address.
Use a location at an intersection a short distance from your home. That way, if your GPS and car are stolen... the bad guys can't use it to find your house.
If you like to shop GARAGE SALES...... the night before, program all the addresses into your GPS. Makes finding all those bargains a lot easier. (We're finding that a lot more people advertise their garage sales on Craig's List than in the newspaper)
Tired of the kids asking: "Are we there yet"? Just program in the address of your destination and your GPS will show you your arrival time, miles to destination, miles traveled, speed, average speed, even a colorful map. On the other hand, a GPS may cause the kids to ask more questions.
