If you want to turn your netbook or conventional laptop into a nifty open source navigation system, you need two things: a USB receiver and a GPS-enabled navigation application. You can buy a GPS receiver cheaply at virtually any gadget store or on eBay. And there are actually several GPS-enabled navigation applications out there, including Navit, GPSdrive, and Roadnav. These are fine applications, but if you are looking for GPS software that offers the right amount of features wrapped in a sleek and user-friendly interface, try tangoGPS. This lightweight GPS-enabled navigation application can pull maps from different sources and has a few clever features up its sleeve.
