If you're the type who could get lost in your own backyard and still refuse to ask for directions, then Delorme's Street Atlas USA 6.0 with Earthmate GPS Receiver may be just what you need. Street Atlas USA is mapping software that allows you to plot a route between any two addresses in the United States and receive detailed, step-by-step directions.
When used with a laptop PC and the ultra-portable Earthmate GPS receiver, Street Atlas tracks your travel path with a moving arrow and provides voice navigation cues, a virtual backseat driver. The Street Atlas software is included free with Earthmate, which requires four AAA batteries and plugs directly into the serial port of your laptop.
