Better get yourself a dedicated GPS before they no longer exist. Since you can find them built into smartphones and other devices, we may not see them for much longer. And if you happen to want one, check out the Magellan RoadMate 5175T-LM.
It features Wi-Fi connectivity so you can download maps and updates when you are within a wireless hotspot. It sports a large 5″ high resolution touchscreen display as well as many unique applications that help you do things like find your local favorite places and more.
