UPDATED 20100719 : Raw logging is also available on the nuvi 37xx series, see details on page 49
UPDATED 20091106 : Member adamschneider has created a facility in GPS Visualizer that can read and output the gps.bin files generated by the Garmin Nuvi devices.
Convert to GPX: http://www.gpsvisualizer.com/convert?convert_output=gpx
Draw a Google Map: http://www.gpsvisualizer.com/map_input?form=google
Make a KML file: http://www.gpsvisualizer.com/map_input?form=googleearth
The nav.bin files are NOT supported.
UPDATED 20090725 : The hidden data logger can be activated on the nuvi 1xxx series by a long press on the "compass" on the left side of the "trip computer" screen. As usual you need a satellite lock to activate recording.
UPDATED 20090429 : Forum member HalliHallo has kindly compiled a PDF document summarizing the contents of this topic click >> HERE << to view it.
Note that on the 2x5 models the gps.bin file is in \debug
UPDATED 20090406 : It turns out the hidden raw data logger has been there all the time, as an "easter egg" requiring a specific sequence that dcnuvi found by accident and that emmexx managed to recreate :
quote:
Enter "Where am I" (from the tools menu or clicking on the arrow icon on the navigation map)
then click in the following order on:
1. Nearest Junction (header of Nearest Junction/Intersection)
2. Nearest Address (header of Nearest Address)
3. Nearest Address (header of Nearest Address)
4. Nearest Junction (header of Nearest Junction/Intersection)
Bingo, the logging menu is there !
If you make a mistake you must exit the "Where am I" menu and start again. As a side effect the "screen shot" icon appears.
[ed]It's fairly obvious but it puzzled me at first, if you don't have a fix, the menus are greyed out unless logging is already active. I noticed it survives a restart and that you can deactivate the screenshot feature in tools/settings/display.
Tested so far on the nuvi 2x5, 2x5w, 550, 760, 755.
UPDATED 20090316 : Raw Tracklog can be now be enabled again on the nuvi 7x0 with software v4.60, see details on page 28.
REMINDER : as suggested by a forum member, this has already been discussed before, but a reminder can never hurt, flashing your GPS with an unofficial firmware version (be it to enable the raw logger or revive your dead GPSwith the "cure firmware) is something you are doing under your sole responsibility and it means you will not be able to get support from Garmin in case of a problem with your GPS in the future.
TIP - ACTIVATING HIDDEN TRACK LOG FEATURE

Compared to nüvi 7xx built-in logger : >> DETAILS <<
UPDATED 20080526 - popej has added a GUI to his nuvitrak tool, details here on page 14.
UPDATED 20080205 - HOW TO KEEP THE HIDDEN LOGGER WHEN UPDATING : quite by accident I realized that the "hidden track log" feature that was quickly removed by Garmin actually survives a software update, provided the logging mode was active prior to the update. z.entropic wrote a how to if you want to use that trick and popej updated his nutrak conversion tool.
UPDATED 20071117 : the v3.50 update for the 2xx series REMOVES the hidden logging mode, see here for the changelog from v3.40 to v3.50.
UPDATED 20071111 : hidden log feature can be activated on the 7xx series too, tested to work with FW2.20. Compared to the built-in track feature it records the raw data apparently, not the "snapped to road" data.
NOTE BY GPSPASSION : track recorded in binary format, use the tool written by popej to convert to .gpx, link is below.
I just updated my Nuvi 250 to 3.40 and I notice that Garmin has added the possibility to record the travel log. This features could be found in the hidden menu which could be accessed by pressing and holding on the speedometer for about 10 sec. Press next to go to the Travel log screen. From this, I could start a new log or replay an existing log. I haven't tried to connect the Nuvi to the PC to see what I could do with the log files. Does anyone has more experience with this new feature?

Play back in progress:
REMINDER 20120707 : Jotne reports that if you leave the hidden track log stored in the internal memory of your Nuvi it can grow in size over time. It is possible that the file can become so big that little free space remains in internal storage and this can cause the unit to slow down considerably. Of course this is a much bigger issue on devices with only 2GB of internal storage space. |

Wow is right. I'll bet jotne has already pressed a hole in the screen trying to reach that page [grin]. I know I did. I have fired up both the 350 and 680, running 5.0 and 4.10, and no luck.

I'll have to update my 250 to see what it looks like.
I'll be back. |

I just upgraded, this trick works on my 200. The caveat is that after I recorded a log, when I went to play it back it did a "data abort" shut down. It restarted fine though.
It's actually the Speedometer you hold down, on the 200 at least. The first page is a list of error dates/info. The second page is the track page.
To get to the speedometer page, from the mapping page you click on the arrival time/speed part on the bottom left corner. Then if you hold your finger over the speedometer, compass, or just the top left corner for 8-10 seconds it will take you to the hidden screens. |

Although pressing the top left corner of the Speedo screen brings up a ton of information on my 350 running 5.00, none of it seems to be 'track' related. Oh well , thinking about getting a 750/60 for Christmas anyway.  |

Thanks... |

Nice catch, works on a euro 250 too and I also had the initial "reboot". Must be some type of debugging mode or they're thinking of adding it as an official feature in the future ;-)
The bad news is that it gets recorded (in \Garmin\Logs\) as a binary gps.bin file that can't be opened with a text editor so you couldn't use it to geotag your pictures.

File format of gps.bin is very simple, no problem with conversion to gpx. It goes like this:
Header 48 bytes:
4B string - text "BEGN"
4B int - GPS week number, starting at 22.8.1999
4B int - second of a week
4B float - heading in radians
8B double - longitude in radians
8B double - latitude in radians
12B ??
4B int - 0 or number of records
record 28 bytes:
4B string - text "$$$$"
4B int - timestamp in miliseconds
8B double - latitude in radians
8B double - longitude in radians
4B float - heading in radians

WOW! Nice finding. And thanks Popej for these explanations.
Unfortunately I don’t have Mapsource, do you think it would be possible to convert these data for reading them with Google Earth or with another free software?

[TIP] Raw logging on nuvi 2xx/5xx/7xx/1xxx/37xx
