I have a simple Garmin vehicle-type GPS that is helpful in urban area but not much use on bush roads. If you are driving on a road that does not exist it just shows you driving on a blank screen. There are also lots of roads shown on the GPS screen that were never there or were overgrown 30 years ago and are now just forest.

It is a handy tool in the bush though to be able to get your location (Lat/Long) from the GPS and use the map to figure out where you are.
