On February 10, 2012, Garmin released a software update for the eTrex 20 and 30. Software version 2.61 provides an improved GPS response at low speeds. With the latest software, users should be able to receive a stronger GPS signal than before. The update requires an IBM-compatible PC running Windows XP or later operating system and an available USB port.
The eTrex 20 and 30 were announced in late May 2011, becoming the latest generation of the popular outdoor eTrex line. The two models share the same high-end features like a bright color screen, microSD slot for additional memory storage, and a rugged, waterproof housing made to withstand the elements. In addition, the eTrex 30 offers the ability to wirelessly transfer waypoints, routes, geocaches, and tracks along with a built-in electronic compass and barometric altimeter.
Note: Although this software is believed to be reliable, Garmin warns it is still in the Beta testing phase and has not been released for production. Although no major problems are expected, users are warned to use at their own risk.
