After taking a few winding turns, she realized that she was nowhere near home. But she did not panic. She had recently installed one of the new GPS units and that helped her reach home without much hassle.The above-mentioned scenario is not uncommon and could happen to anyone. In such situations, a GPS unit can come to your rescue. Whether you are going for a road trip to a distant place, have a bad sense of direction, are on a safari for hunting or just in an unfamiliar city, all you need is a GPS navigation unit as your friend and guide (pun intended!). For those of you who do not know what is a GPS, here is the answer.
