While all GPS receivers can tell where you are, entry-level models have no way of ascertaining which direction you are facing. So you have to start moving and walk a few steps at a good pace before it can accurately point you towards your destination. This is why mid-range and high-end units have an electronic compass — to show the direction you should travel even while standing still.
This can be found in any GPS operation information. Compass Needed !!!And so back to the Magnetic Compass.GPS manufacturers recognise that whilst a differential compass is fine most of the time, users still like the security of a magnetic compass. The traditional magnetic compass has been fitted with electronic sensors and bundled into some of the GPS devices. This is what is meant when a GPS is advertised with an electronic compass. It costs a little more but allows you to take bearings when stationary or out of sight of the satellites.
Hope this helps
