Garmin Nuvi 200 Track Hack

After having the Garmin Nuvi 200 for a while now, I have come across a really handy feature. The feature allows you track your routes on your Garmin Nuvi 200. This is a hidden feature, so it is still relatively unknown.
YOU NEED TO ENSURE YOU HAVE FIRMWARE VERSION 3.40 OTHERWISE THIS WON’T WORK. To check what firmware version you have, do the following: Menu->Settings->System->About. Here it will show you the version number. If the version number is not 3.40 this will not work. If you need to roll back to version 3.40 to enable track logs, download the firmware HERE

To get to the track feature on the Garmin Nuvi 200, do the following:

1. Select a destination you want to drive to.
2. On your view map screen, press the Arrival time button in the bottom left corner
   
3. This will bring you to the Speedometer Screen. Once in this scree, press and hold the screen for 8-10 seconds over the speedometer.
   
4. This will bring you into the Garmin Diagnostic Menu. DO NOT change anything here. Click the Next button at the bottom.
5. At the next screen, you will see the “Logging Control” screen. Press “START RECORDING” to start recording your track
   
6. Once you have completed the trip, press the STOP button on the main map screen.
7. Connect your Garmin Nuvi 200 up to your computer via a USB cable.
8. Go to the Garmin Nuvi 200 drive, and browse to the X:\Garmin\Logs (Where X:\ is the disk drive of the Garmin)
9. Go into the latest created folder, and download the gps.bin file.
10. Download Nutrak from this site. Extract the contents of the zip file to a folder on your Computer
11. Go to the command prompt (Start-> Run-> “cmd”) and go to the folder where you extracted Nutrak.
12. In the command prompt type “nutrak.exe gps.bin”. This will create a .gpx file.
13. Open Google Earth
14. In Google Earth, click File, Open and browse to the .gpx file that was created.
15. You will now be able to see where you have driven in the track you have created.
    
    This is an example of a track I created.
