The eTrex is a now-discontinued handheld global positioning system (GPS) device. A portable GPS such as the eTrex is favoured by hikers, boaters and outdoor enthusiasts as a navigational aid. One feature of the eTrex is the ability to hook up the unit to a personal computer for downloading map images and coordinates. The eTrex is equipped with a computer serial port for this connection. Since most modern computers no longer come with a serial port, you'll probably need a serial to USB adaptor cable. These plug-and-play cables require no special drivers or software.
