A really neat site where all sorts of great details on inner workings of most all significant hand-held navigation devices. What may be of interest is that over the years when I was hunting down a rumor, trying to discover recoveries to bad behaviors in new products, or to monitor the day-to-day of my personal GPS interest, GpsPassion, can, IMHO, be relied on.Here is a nugget that seems to suggest that there are some hidden RAW GPS logs within many Nuvi models. Importanty, for some models the normal update process sometimes eliminates this particular and very useful Easter Egg?
Also please BE AWARE that some of the propeller-heads doing these neat hacks of the Garmin PDNs and other manufacturer models are not always greeted well by the manufacturer to recover PROM installs gone wrong...
| 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: 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. 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? Log screen - Logging in progress: Log entries - Play back param:   Play back in progress:  |
