He He but they can be quite dangerous in aus in the country. Just recently a couple had to be rescued up a country dirt road as they had plugged into their sat nave the shortest route home to Melbourne and ended up on fire tracks in the hills.
My son who lives in the country in the mallee said that they locals hate they have to keep looking for city people who are relying on their sat navs.
People have trialled them and say they take them round the world to get to where they know is very short.
They are also only as good as the maps loaded in.
I will stick to the maps
