This unit works just as advertised and is very accurate. Set up was reletively easy. All you have to do is install a couple small programs on your PC (I have Vista on my PC and the SW works great)and provide a link to Google Earth. Calibration of the GPS is about 5 simple steps. If you want a device to do that with, plan on spending more for the GPS device as well as maintaining a service with a cell provider exclusive for the device.
