I am looking for a gps car unit and am totally confused. Just when I think I found the right one I read the reviews and change my mind again. I keep going back and forth on garmin vs tomtom vs magellan. Who has the best routing? Which units have the easiest map updates? I have tried to use a gps app on my tablet but it does not cache the maps well and sucks up battery power. So now i am looking at dedicated gps units. I am just looking for a unit that will get me from point a to point b and to point out gas stations and campgrounds/stateparks. I would like to stay within the $100-150 price range Any advice or input is appreciated.
