Uploading and Downloading Garmin eTrex 20x Data

Download your Garmin eTrex 20x waypoints, routes, and tracks to your computer

ExpertGPS can transfer Garmin eTrex 20x waypoints, routes, and tracks through your computer's USB port. It only takes a second or two to download all of the data from your Garmin using ExpertGPS.

Upload new waypoints, routes, and tracks to your Garmin GPS

Transfer data back to your Garmin eTrex 20x with a single click. Upload waypoints, routes, and tracks to your GPS and print a matching map out to take with you into the field. ExpertGPS even lets you upload Excel, Google Earth, CAD, and GIS data to your Garmin eTrex 20x!


Maximize your GPS Memory

Your Garmin eTrex 20x has limited storage space for waypoints, routes, and tracks. Once you reach that limit, your GPS can't hold any more data. Smart ExpertGPS users have figured out how to eke out every last bit of memory space on their Garmin GPS receivers. Before each outdoor adventure or visit to a project site, they use ExpertGPS to back up the contents of their GPS, and then clear the GPS data memory. They can then download as much data as possible onto their GPS (leaving some room for GPS data collection out in the field). When they get back, they use ExpertGPS to upload all of their Garmin waypoints, routes, and tracks onto their computer and save it. Once they've backed up the new data from their GPS, they can clear the memory again, keeping their GPS ready for their next trip.

Backup your Garmin eTrex 20x waypoints, routes, and tracks

Backup your eTrex 20x waypoints, routes, and tracks by using ExpertGPS to transfer them to your laptop or desktop computer. Now you've got a safe back-up of all of the important data on your eTrex 20x, and use ExpertGPS to find and create new waypoints, routes, and tracks to download to your Garmin GPS. Before you update your Garmin eTrex 20x firmware or install a custom basemap, Garmin recommends that you backup all of your GPS data. ExpertGPS gives you the peace-of-mind that your Garmin eTrex 20x data is always safe.


Making Maps from your Garmin eTrex 20x Data

Real 1:24000 USGS Topo Maps

View your Garmin eTrex 20x waypoints, routes, and tracks over USGS topo maps and aerial photos. These are actual 1:24000 scale topographic maps from the US Geological Survey, giving you much more terrain detail than the maps that came with your Garmin.

Toggle between Topo, Aerial, and Color Orthophotos

Instantly switch between topo maps, aerial photos, and color urban imagery using the T, A, and U keys in ExpertGPS. This ability to toggle back-and-forth between several views of your GPS data is unique to ExpertGPS, and is one of its most popular features.

Give your maps a professional look

ExpertGPS comes preloaded with all the line patterns and cartographic styles you need to draw highways, railroad tracks, transmission lines, streams, and more. And the waypoint and track style editors let you create your own map symbols, change track colors, and customize exactly how your GPS and map data is drawn.


Boost your Garmin GPS data entry speed 500%!

Why waste time entering new waypoints on the tiny screen of your Garmin eTrex 20x? ExpertGPS can do it 5x faster! Use the New Waypoint dialog in ExpertGPS to create new waypoints and POI listings for your Garmin GPS. As you type, ExpertGPS automatically suggests the best possible name for this waypoint on your GPS.


Calculating Area with your Garmin eTrex 20x

Calculate Area (Acreage) using your Garmin eTrex 20x

Calculate area with your Garmin eTrex 20x. ExpertGPS automatically calculates the acreage of any parcel, field, or tract no matter how irregular, when you record the boundary with your Garmin eTrex 20x or trace it over the maps in ExpertGPS. ExpertGPS allows you to calculate acreage in three different ways:
1. Calculate area by walking a perimeter with your GPS. ExpertGPS calculates the acreage enclosed by your Garmin eTrex 20x tracklog.
2. Calculate area by marking GPS waypoints at the corners of a field or parcel. In ExpertGPS, connect those waypoints into a route, and the acreage is automatically calculated.
3. Calculate area by tracing over a map or aerial photo. Use the Track Tool in ExpertGPS to trace the property boundary or field, and let ExpertGPS calculate the number of square feet it encloses.


Garmin eTrex 20x Waypoints and POIs


Maximize your Garmin waypoints

ExpertGPS lets you get the most out of the waypoints on your Garmin eTrex 20x by making it easy to assign the best symbol and to give each waypoint a long, meaningful name (using a real keyboard, not the little controls on your GPS). Think about it:

Your Garmin eTrex 20x can hold 1000 waypoints. Waypoints on the Garmin eTrex 20x can contain up to 32 characters. Waypoint comments (notes) can contain up to 32 characters. How long would it take you to enter all of those waypoints by hand into your GPS? ExpertGPS will save you hours on this one task alone!

Add Photos and Notes to your waypoints

ExpertGPS lets you link a photo to any waypoint or POI and includes a built-in photo viewer. And you can add your own detailed description to any waypoint - store as much information as you need.

Prevent Data Entry Errors with ExpertGPS

GPS coordinates are easy to mis-type. Using the Waypoint Tool in ExpertGPS to create new waypoints reduces the chances of making a mistake when manually entering coordinates on your GPS. ExpertGPS takes care of all of the coordinate conversion and datum shifts when communicating with your Garmin eTrex 20x, further reducing errors.

Create routes the easy way!

The Garmin eTrex 20x can hold 50 routes, each containing up to 250 turns or stops. ExpertGPS lets you build up long routes quickly - just click waypoints one-by-one on the map to connect them into a route for your Garmin eTrex 20x. Route names on the Garmin eTrex 20x can contain up to 32 characters. ExpertGPS makes it easy to rename and organize your routes.


Tracklog Tricks for your Garmin eTrex 20x

Trace new trails and roads to send to your Garmin eTrex 20x

Did you know you could trace roads, trails, and other features on the maps in ExpertGPS, and send them directly to your Garmin eTrex 20x? This is a quick and easy way to keep you on-track when out in the field.

Fix up GPS errors in your Garmin tracklog

Poor GPS satellite reception can cause all sorts of errors in your Garmin eTrex 20x tracks. Use the advanced track editing tools in ExpertGPS to correct spikes and blips caused by intermittent GPS multipath errors. You can even select an entire segment of your GPS track and drag it right back to its correct location on the map!

Tracklog Specifications for your Garmin eTrex 20x

The Garmin eTrex 20x can hold 501 tracks. Saved tracklogs on the Garmin eTrex 20x can have up to 10000 trackpoints. The active tracklog holds 10000 trackpoints. Track names on the Garmin eTrex 20x can contain up to 32 characters.


Geotagging Photos with your Garmin eTrex 20x

Save Hundreds of $$$ with Geotagging Software

You can spend hundreds of dollars on dedicated camera hardware and cables to geotag your photos. Or, you can do it for free, using ExpertGPS. ExpertGPS automatically matches up the timestamps on your digital photos with the times recorded in your Garmin eTrex 20x track log. It just takes a few seconds when you get back to your desk to have ExpertGPS automatically geotag your photos.

Share your Photos on Flickr and Google Earth

Photos geotagged using ExpertGPS are 100% compatible with flickr.com, Google Earth, and any other geotagging software or Web site.

Batch-Edit your Photo Metadata

ExpertGPS lets you quickly view, change, or batch-edit your photo metadata. Select all the photos for the day, and quickly add the city, state, and location in which they were taken. Add and remove keywords and descriptions. View shutter speed, aperture, and other camera settings.

Revolutionize the way you collect data in the field

Still using paper forms, or typing data into your GPS piece-by-piece? With your digital camera around your neck, Garmin eTrex 20x in your backpack or in your vehicle, and ExpertGPS back at your desk, you can gather data on the move. There's no need to mark waypoints as you collect data - just snap photos at each site. ExpertGPS can create geo-referenced waypoints for your report from each photo you took along the way, and attach your photos to each waypoint it creates.


Garmin eTrex 20x Coordinate Conversion

Convert between any coordinate format or datum

Need to convert NAD27 lat/lon to WGS84 UTM? ExpertGPS does it automatically. Enter coordinates in any format, in any datum. To convert Garmin eTrex 20x coordinates to any other format, just select that format in ExpertGPS. All of your data is automatically reprojected to the new format and datum.

Convert to and from US State Plane Coordinates

ExpertGPS Pro lets you work with data in any US State Plane Coordinate System (SPCS). Even though your Garmin eTrex 20x doesn't natively support SPCS, you can use ExpertGPS Pro to convert data back and forth between state plane coordinates, lat/lon, and UTM.

Convert any address to latitude and longitude for your Garmin eTrex 20x

ExpertGPS converts addresses to GPS coordinates with its built-in address geocoder. Enter any address in the US (or in several dozen other countries) and ExpertGPS will bring up a map of that location and create a GPS waypoint you can send to your Garmin eTrex 20x.

Locate property using PLSS (Township, Range, Section) coordinates

The Go to TRS command in ExpertGPS Pro will take you directly to any township and range in 17 western US states, allowing you to locate land in the US Public Land Survey System quickly. As you move over the map, the current township, range, and section is displayed. ExpertGPS Pro can even overlay a PLSS grid from BLM or your state GIS department.


Viewing Garmin eTrex 20x Data in Google Earth

View your Garmin eTrex 20x data in Google Earth

With ExpertGPS, you'll be able to view all of your hiking trips over the aerial photos in Google Earth, showing exactly where you went. This feature is so popular in ExpertGPS, we've added a hot key (F7) that will automatically launch Google Earth and zoom in on your hiking waypoints and tracklogs. And, we've also added the ability to download KML files back to your Garmin eTrex 20x


Layering Garmin eTrex 20x Data with GIS Data

Convert Garmin eTrex 20x waypoints and tracks to ArcGIS SHP format

ExpertGPS makes it easy to update your GIS database with GPS data recorded in the field. Simply mark waypoints or record a tracklog on your Garmin eTrex 20x, and then use ExpertGPS to upload your GPS data and export it as a shapefile. And you can Send GIS layers to your Garmin eTrex 20x as well.

We use open source maps downloaded to our Garmin GPS. A friend taught us how to download free maps to our GPS when we were in Mexico. We are forever indebted to him for showing us how to do this. It saved us lots of money since we didn’t have to purchase the maps from Garmin and the open source maps are updated more frequently. I have passed on the how-to steps to individuals along the way and wanted to share the information more broadly. So, here we present step-by-step instructions.

Using Open Source Street Maps for use on a Garmin

Step 1: Go to Open Street Map Website: http://garmin.openstreetmap.nl

Step 2: Choose your map type – click “generic routable (new style)”

Etrex 20x Garmin Download Road On Mac 7

Step 3: You have two choices at this point – you can download a pre-defined country or build your own custom map.

Choice 1 – a predefined country
• Using the drop down choices pick your country and depending on size you might be able to immediately download the file
• Example, using the Asia drop down, choose “Laos” and then at step 4 (request map) you will see “download map now” link on the screen immediately. Note: download map now does not always work so see step 4.
• Click on the download map now link and another window will open
• Download the file with the name “osm_generic_new_gmapsupp.zip” and the description says “compressed file containing a single image that can be placed directly onto the SD card of the GPS”. On my MAC it downloads as an image and not as a zip file so it is easy to place in the folder; this might be different on a PC.

Choice 2 – build your own map
• Click the box “enable tile selection”

• Then using the map area below – use the up and down arrows to move around the world map and the + or – to zoom in or out – click on the tiles you want. For example, I built maps of all the Southeast Asia countries I wanted to drive through.
• Once you have selected your area then request your map

Step 4: Requesting your map


• Fill in your email address and click build my map
• After your click “build my map” another window will open that says you will receive two emails

Step 5: Receiving your map
• The first email you receive will tell you that your map is in process and provide a link that you can check when it will be ready or its status
• The second email you receive will give you a link to go download your map

Step 6: Downloading your map
• Click on the link in the email
• Download the file with the name “osm_generic_new_gmapsupp.zip” and the description says “compressed file containing a single image that can be placed directly onto the SD card of the GPS”. On my MAC it downloads as an image and not as a zip file so it is easy to place in the folder; this might be different on a PC.

Step 7: Put map on the SD card for your Garmin
• You now have the file. Do not change the file name in any way; if you do then it won’t work.
• Put your SD card in your computer and make a folder with the name “Garmin”; do not give it any other name or it won’t work
• If you are using the SD card that was already in your Garmin then open that folder marked “Garmin” and delete the image file that is in the folder. If this is a map you have purchased then save it your computer.
• Move the new file/image that you downloaded onto the SD card into the folder marked “Garmin”
• Put the SD card back into your Garmin and you now have your new map

Step 8: On your Garmin device
• Insert the SD card into your Garmin device (or turn off/on if you saved to the device hard drive).
• Turn on device
• Scroll until you find tab called “setup”, click on that
• Scroll until you find tab called “map”, click to open
• Select button that says “map information” (may also say select map) click to open
• In this field you will see all maps that are on the device. Find the map you want to use (“OSM generic routable (new style)”), select it in order to “enable it”
• Any other maps you have on your device, you need to select and choose “disable” otherwise there can possibly be mapping conflicts.

Troubleshooting:
• The main issue that can happen is that the map isn’t working. The usual issue is that the Garmin is confused because there is more than one map on the Garmin. You have already made sure that the SD card has only one image and that the folder is called “garmin” and there shouldn’t be any other folders on that SD card. If it still isn’t working then plug your Garmin into your computer and look at the files on its hard drive. If there is another file named “garmin” then this is where your conflict is occurring. Remove that file (make a copy of anything you are deleting before deletion as you may need it later).

• I did this on one person’s Garmin device that didn’t have an SD card so we were putting the new map image into a “garmin” folder on the hard drive. But, before I did that I deleted the old files (before deleting I had saved a copy onto my computer). What I didn’t realize is that the old file had contained information that would put the map image into different languages. He needed his map to be in French. I was able to go back and move over the language files onto his Garmin from the folder I had taken off. I got help doing this from a YouTube video after searching for adding languages to a Garmin.
