. Spanner overcomes this by creating a virtual serial port and thereby allowing a USB based Garmin GPS receiver ‘speak’ with programs that require NMEA data.

Spanner is offered as a tool for Garmin’s GPS 18 product, but it works with other Garmin GPS receivers including the GPS 20x, GPSMap 60cx, 76CS, Colorado series (software version 2.51(beta) or later is needed) and Oregon series.
