First of all I usually use red as my track color. You can edit my replacement file to suit your needs.
1. Go to http://xml-copy-editor.sourceforge.net and download this XML editor. It is very simple and it works very well, it is free and I have found no spyware problems; however, I always run any download through 3 different spyware and virus checkers, you should do the same.
2. Hook up your unit to Basecamp.
3. If you have bad XML files, make a note of the listed bad tracks that Basecamp provides when it reads your GPS.
4. Open windows explorer.
5. Go to your Garmin instrument or to the micro SD card (where ever you have these bad tracks stored.) I keep mine in my Oregon 550 and not my SD card.
6. Expand your Garmin instrument file or your removable disk file and click on the “Garmin” folder.
7. In the “Garmin” folder click on “GPX” sub folder.
8. Your list of tracks should be here in the “GPX” folder or in the “archive” sub folder.
9. After installing XML Copy Editor, launch it.
10. Click on “OPEN” and go to windows explorer where you have found your bad track files.
11. Using your Basecamp list of bad tracks, open 1 or several files (you can open more than 1) into XML Copy Editor.
12. The first thing you will see is a command line with a red line under it; this is the bad command.
13. Highlight and delete everything between the commands <extensions> and </extensions>. Be sure to leave <extensions> and </extensions> and <trkseg> or any other commands intact.
14. Copy the lines below and paste them in between the <extensions> and the </extensions> lines. Note: the track color “Red” is listed twice. You can edit this color to suit your needs.
<gpxtrx:TrackExtension xmlns:gpxtrx="www.garmin.com/.../v3">
<gpxtrx:DisplayColor>Red</gpxtrx:DisplayColor></gpxtrx:TrackExtension>
<gpxx:TrackExtension xmlns:gpxx="www.garmin.com/.../v3">
<gpxx:DisplayColor>Red</gpxx:DisplayColor>
</gpxx:TrackExtension>
15. You will notice that the red underline goes away. To verify that this new track is written well, click on the 2 green check marks, one at a time, in the top tool bar and read the result of each on the bottom tool bar of XML Copy Editor.
16. Click on “File” in the top tool bar.
17. Click on “Save as”.
18. The “Save as” box will appear and it should be the file in your Garmin instrument folder where you originally opened the file you are working on in XML Copy Editor.
19. Click the save button.
20. It will ask if you want to replace the existing file; say “YES”.
21. You’re done with this file. Repeat as necessary.
22. When you are done with all the files, unplug your GPS and then plug it in again and let Basecamp read your tracks
23. You should have no error messages.
Until Garmin comes up with a real solution, I hope this helps anyone who is having the same problem I’ve been having. Please let me know if this fix works for you.
