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
nüvi 2xx, nüvi 7xx
 
Useful links :
Decoding tool programmed by popej : >> DETAILS <<
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. |

With the topic being 53 pages, I'd have to read through the whole thing to refresh myself as I certainly don't have a photographic memory. Maybe popej has one... |

Lack of reading comprehension on my part, no doubt. I never looked at the date on the post prior to the one about the firmware version.
Sorry |

My question is, what does any of this have to do with the question Fuse posted today about loosing raw logging if he updates the firmware to 5.10. I'm a bit confused as to why that post got a conversation going about encryption which seems to stem from a post that's more than 2 months old. |

Sorry, you have lost your bet ;)
Read pages 8, 9 of this thread.

Well that's not likely to be an encryption, per-se, but a data packing technique such as zip or similar. Why would there be any need to ad the excess program overhead of encrypting the binary tracklog? It serves no purpose. Packing the data to take less space, however, serves a very useful and necessary purpose. My bet is on this rather than an encryption algorithm. |

Why do you think it is not encrypted, have you looked at data?
Well, it is encrypted. If i remember correctly it is like byte XOR with a value, which is constant for several bytes and then increases with irregular intervals. |

If somebody knows the type of encryption I am willing to work on it to decrypt the data.
Why would you think it's encrypted? It's probably just in a binary format you don't recognise. |

Hello!
I have Nuvi 260, HWID = 0660, version 5.0 with patch (066001000500_sd.rgn), which opens the raw logging. Yesterday I installed the Garmin.Express on my PC, who wants to upgrade a software to 5.10. But I'm afraid of losing raw logging. Will the raw logging is also available in the software version 5.10 for my Nuvi 260?
Thx! |

No change. There is gpx mode in new devices, understanding bin is not necessary to have a tracklog.

Popej, any updates on converting the raw (.bin) track logs from the newer units (37xx/35xx)? |

Not sure but the author will know the answer ;-) |

Zumo owners will definitely find this useful. Now, how about a Mac version [g]?

Thanks for the tip indeed, here's another one on a related topic : the latest version of Pixel K's GPX Editor (beta section) has a very useful new feature for those trying to extract a meaningful track from the GPX archives recorded by Garmin nuvi (and maybe other) GPS systems. It's a "rolling" archive so it means there well be some "backtracking" going on when they are assembled as well as many data points being doubled up. Now a simple right click will take care of this problem. |

Thanks for the heads up. First post has been updated. |
