GPS - Global Positioning System
similar to a road angel only better and more advanced
basically it works out your position from the relative position of certain satelites orbitting the earth to an accuracy of approx. 30foot
you give it a destination
then it gives you voice directions to get you there - turn left - turn right - next roundabout take the 3rd exit - turn around you missed the turning ya muppet - stuff like that
also tells you stuff like exactly what time you will get there - how many miles to get there
warns you if there is a speed camera coming up and what the speed limit is
also tells you what speed you are travelling at much more accurately than your cars speedo
ive used one for the last year or so and i have to say that its one of the best things ive ever bought for the car
no more arguing as soon as we leave the motorway any more :)
always arrive stress free now :D
