“Which route should I take? Left or right? Come on. Help me look at the maps.” Do you still using paper maps as your navigation guide? If yes, you are out of date already. Global Positioning System (GPS) navigation system is the new gadget that you should have. GPS is a very useful tool that provides reliable location. With its frequent updated maps, you will hardly lost again. And I have one GPS model to introduce ~ GPS BAY G73.
