GPS will be in accordance with the routing algorithm to calculate the nearest path, the premise is to have a detailed street map. GPS will tell you the right to turn right at the intersection. Mobile GPS can also search the starting point near the point of interest information, and can calculate the fastest path to reach the land.

If the old section of the handheld GPS feel Magellan's design is more fashionable, the new Magellan with better Ming products have their own characteristics, mainly to see their own habits and tastes.
