Thread: Secret Startup Commands and hidden menus in Garmin devices

[Only registered and activated users can see links. ]

Function of "diagnostic log or tracelog (register the trace of your way without consider the map rote)" in the nuvi 2x5, 2x5w, 550, 750, 755, 765T, 1490, 3760,..., and probally in other models.

I found it in the link:
in english (full explanation) This post requires you to click the "LIKE this post" button and hit F5 to read this content.
in portuguese This post requires you to click the "LIKE this post" button and hit F5 to read this content.

I save in .doc attachment the content of the links.

OBS: This function is mainly useful to build or improve accuracy of current maps. But, if you use this function to normal usage, will disable the tracklock; and old software of GPSs may recalculate several times the rote, what may be disturbing for some… Newer versions of the software to my device don’t make this mistake (I don’t know about other models, but guess the same).
