Need maps for your Edge 810?

We'll send you the OSM maps preloaded onto an SD card for $25. See details and purchase your preloaded OSM maps here.

Quick Summary:

As of May 2013, the Edge 810 has a new software update to fix issues with loading TCX files into the NewFiles folder, per the instructions on this page. Check and make sure you have the newest Firmware from Garmin by visiting this page: Edge 810 Updates and Downloads

If you have a premium account, map a route using our bike route planner and then use the Garmin Write feature to load either a GPX Track if you have Garmin/OSM basemaps or a TCX file if you don't. If you want turn-by-turn directions and have basemaps installed, the following settings on your Edge 810 will help (Settings accessible from Training Profiles->(Your Profile)->Routing:

  1. Activity => Cycling
  2. Calculation Method => Minimize Distance
  3. Lock on Road => No
  4. Avoidance Setup => Disable all (to minimize crazy re-routing)
  5. Recalculate => Off or Prompted (important, or it will shortcut you back home!!! I use prompted, but almost always say no)

Garmin Edge 810 Bicycling Computer

Which file should I use?

An Edge 810 is very similar to the Edge 800 in that it can use a TCX, a GPX Route or a GPX Track. Each have pros and cons so read the descriptions carefully. I strongly recommend trying each format on a simple test route to get a solid feel for pros/cons before using it for navigating a ride. With that being said, you will best be served by a GPX Track if you don't need custom cuesheets from our site, and a TCX if you are attempting to train or want to navigate a route with a custom cuesheet, or if you have an Edge 810 without basemaps.

TCX

Great for navigation if you need custom cuesheet entries or don't have basemaps! Good for soon to be released virtual partner training features.

The TCX format is great if you want to navigate a route from the site which contains custom cuesheet entries. The Edge 810 will navigate you along the route, giving true GPS style navigation with a stylized map containing an overlayed arrow. When you get within 20-30 feet of the cuesheet entry, it will also beep and display the name of the entry. So, you get navigation plus alerts when you come up on your cuesheet entries. One thing to note: the cuesheet entry alert is "dumb" in that it doesn't take into account your direction of travel. Say you get off course and loop around the block, so your left is now a right to get back on course. The cuesheet entry will still say "Left" even though you need to take a "Right". The navigation instructions on the GPS will be correct, but the entry won't. As long as you recognize that limitation, then the TCX is a great format for navigation.

One note: the TCX file is intended as a training aid. The Garmin Edge series will have a "virtual partner" that you are racing against - the partner's speed is set by the timestamps we put in the file. For now this is very basic - we don't set the timestamps to be of any help while training. So if you are just navigating a route, trying to avoid being lost rather than trying to maintain a certain speed, you should turn off virtual partner inside the GPS unit.

GPX Tracks

The best format (aside from TCX, read about that below) for navigation

A GPX Track contains the hundreds of points used to draw a map, but it doesn't contain cuesheet information, so any custom created cuesheet entries will NOT be present when you navigate. However, the GPS unit will strictly follow the plotted route and will also provide you with true navigation style turn by turn instructions if you have CitiNav or OSM base maps installed. You get a stylized map with a superimposed direction arrow at turns, as well as textual directions. Additionally, whether you have base maps or not, the compass on your GPS unit will always point in the direction you need to go and you can see your route plotted on the Edge's map display. As long as you don't need any custom cuesheet entries, this is the best format to use.

GPX Routes

Sub-optimal, not useful for most people

A GPX file contains only the cuesheet points, but doesn't contain the hundreds or thousands of points required to draw the map. Since the GPX Route file only contains the cuesheet notes, the Garmin will use its internal maps to route from cuesheet entry to cuesheet entry. Often times this means it will take different streets than expected, so total overall mileage is almost guaranteed to be shorter. It usually calculates the routes to be as short as possible. As a result, a GPX Route is rarely a desirable format to use on the Edge 810, and we recommend staying away from it unless you know what you are doing. One "benefit" is that the custom cues you create on our course creator will be present, but how the Edge 810 actually routes you between them is anyones guess.

GPXX Routes

Not useful on the Edge 810

This format was useful on earlier GPS units to get past internal point limits, but isn't useful in my testing with the Edge 810. It always wants to shortcut back to beginning of the route, even after the first block...

OK, so how do I get the file on my GPS?

To put a TCX or a GPX file on your Edge 810, export the desired file from our site. Once you have the file saved on your computer (remember where you saved it, whether that's the desktop or downloads folder or wherever), you can transfer it to the Garmin. Every computer is different, but the general idea is that the Edge 810 acts like a USB thumb drive. Plugging it into your computer should allow you to view the files stored on the unit. Once you have it plugged in, open up the "drive" associated with the GPS unit, then open the "Garmin" folder inside the drive. You'll now see a list of several files/folders. One of the folders is called "NewFiles". You should copy (drag the icon) the file to this folder. Once done, safely remove the GPS unit. "Safely remove" means follow your systems instructions for removing a USB flash drive. This, on Windows systems, is usually done by clicking the remove hardware icon in the lower right corner of the screen, next to the clock.

Once the file is transferred to the Edge and the Edge is safely removed from the computer, power the device up. You should be able to find your route under the "Courses" menu. From there it should be fairly self explanatory. Please practice navigating a route with something simple, around your neighborhood, and don't try to do this the first time before a big ride with friends.

Installing Free Open Street Map data

Some people purchased an Edge 810 for cheap because it didn't come with Garmin's City Navigator maps installed. This is fine, because there is a complete and comprehensive set of free maps (wikipedia style user-generated maps) from the Open Street Maps project.

Option 1: Let us do the work.

We'll send you the OSM maps preloaded onto an SD card for $25. See details and purchase your preloaded OSM maps here.

Option 2: Download the maps and load them onto a Micro SD card.

  1. If you haven't already, signup for a free account to get the most from your Edge 810.
  2. Choose a mapset from this link - Since I am in North America, I use either Mantlik's contoured maps or Dave's
  3. You have to enable data recording on the SD card by changing the settings: Settings > Data Recording > Record to memory card.
  4. Place a blank SD card in your Garmin, turn it on and then start the timer. You will need at least a 4GB SD card. This will create the proper directories on the SD card automatically.
  5. Stop the brief activity you just started.
  6. Feel free to revert the "Record to memory card" setting once you have started then stopped the timer.
  7. Plug your Garmin into your computer. Depending on your computer, you will probably be prompted to open a folder to view the files on both the main unit and the SD card. Otherwise, navigate to the drive/folder your computer assigned to your SD card.
  8. After downloading, copy the IMG file to the SD cards "GARMIN" folder that was created earlier.
  9. The SD card can have multiple IMG files on it and you can choose between them in the Edge 810 configuration menu. I kept my names descriptive, "osm_western_us.img". VERY IMPORTANT: keep the name short and free of spaces or odd punctuation - underscores are OK for spaces.
  10. Once the file is copied, safely remove (right click on the icon in the lower right of screen for Windows users) the SD card from your computer.
  11. Insert the card and power up the Garmin.
  12. Go to the configuration menu, then Activity Profiles -> (Your Profile) -> Navigation -> Map -> Map Information/Select Map. Make sure all maps labeled OSM are enabled.
  13. Enjoy!
