One thing I have noticed is all of these map/gps devices use the same data. I live in a small town and if I type in my address all of them are at least 4 blocks off.

Face it. You don't know where you live! Better start worrying. You have documented proof. . . Google Maps has been used in court as part of expert testimony!

I have typed the same address into Google Maps, Mapquest, Apple Maps, my Garmin, and at least one other Gps, and they all give me the wrong address.
