Making use of Etrex tricks and tips can help make certain that you are making the most of your investment.
The first thing that you should do when you purchase your Etrex is to make certain you buy all of the discount priced Garmin GPS accessories you need to get the most out of your device.
As the Etrex has known battery problems due to engine vibrations, you will want to make certain that you purchase a power adapter for your Etrex so you have power while your vehicle is running. You will also want to purchase a cable to attach between your Etrex and your computer. This will let you easily update your maps and routes, which is highly useful when you are out on the roads.
There are more Etrex tricks and tips that you should also know about prior to leaving for your trip.
First, you need to know how GPS works so you are getting the most out of the device. The Etrex system communicates with satellites in orbit around the Earth. When this occurs, the satellite returns a signal to the device, relaying its current position.
Your Etrex unit then looks at that information and transforms it into a form that is useful for you. Due to the nature of satellites, there are a few places this won't work well. Blind spots in some mountains, caves and tunnels, and some spots in cities may not work properly.
If you are finding that you cannot get a signal and have tried everything else, move and see if that helps restore the signal. If you still need more information on your unit, try contacting the merchant that you purchased it from.
