The Garmin Etrex computer interface is designed to be user friendly, allowing you to do more than work on getting driving directions and terrain information.
This system works with the Garmin Etrex GPS units, as well as with all Garmin GPS accessories. Before you purchase a system, however, it is in your best interest to compare laptop GPS systems with the Etrex system so that you understand how the system functions.
Doing this, regardless of which system you invest in, helps you grasp the various interfaces more easily.
The first thing you should look for when comparing the Etrex computer interface with other systems is functionality. The Etrex system comes with all of the bases that you need to make full use of your GPS device. It allows you to get the directions you need, as well as pinpoint your exact location.
With memory cards to transfer data from your computer to your hand held unit, you can have a variety of different maps for use with your GPS system. The most important thing to look for is that the systems have everything that you need to use the system to its fullest extent.
If you need more advanced maps and driving directions, you may need to upgrade your software, as the base software covers the basics, leaving some of the advanced features to software upgrades provided by Garmin as well as other companies. Before you buy any software upgrades, however, you should make certain that you need them. Many do not need the upgrades, as the pre-packaged software has everything most people need.
