    New thing, related to my finding:
    even with cure firmware my unit do not recognized by PC. More, when i found this workaround, unit not connected to PC, behavior was exactly same as after unsuccessful maps upgrade. So, if anyone has Nuvi, which needs to be cured, lets try my method WITHOUT cure firmware. And please report results here

    @ esfranky

    Downloaded for example Notepad++ (also download Hex Editor Plugin) and open the file 82701000720.rgn. Change Notepad to Hex and after that use "CTRL + F" to activate the search function. Then find and replace everywhere the strings I wrote in post 2. This one "30 00 3A 00 2F" to this one "00 00 3A 00 2F" etc....Then save and that is all.

    @ esfranky

    First please answer this questions:

    1. What did you do last to the nuvi to reach that condition? This is really very important. Did you format your nuvi for example in NTFS? Did you copy maps, POI etc in its memori.? Did you update its firmware? Be specific please. (Hope I understand your comment correct - nuvi reboots when turned on and not possible to be connected to PC. But when an SD card is pulled in it boots normal but still not possible to be connected to PC. Am I correct?)

    2. Which firmware is using your nuvi? Which HwId? 1091 or 827?

    3. What steps did you try to recover your nuvi?

    I have an idea but please first answer this questions.

    Hello, first, the Nuvi is not mine, I helped through my blog ([Only registered and activated users can see links. ]) in Spanish

    I'll give user feedback

    hi everyone I am new to these conflicts, I was told that the gps as a computer, and as I did not carry me back up and format, does not start lights and try to load the maps and I get (
    Detailed maps not found and many more things you can do something to revive thank everyone in advance
    not recognized by the PC, turn on and off attempts to load, so continuously, if I can turn it off I put the Target
    I got to the Target that works well, but comes in English and has no voice or leave the radar
    The program is fast IMG Unlocker 2.0, placed in a folder and a gampsupp.img garmin. loads only and the time is loaded
    can be made lake, they told me to let it drain the battery and turn
    thank you very much coseguimos aver if that works, there are several with the same problem
    Europe is working for me NT CN 2011.32, is it about Target,
    esque rare but not detected pc.si remove the Target is set to restart and unfinished turns off and reboots, so continually drain the battery pole.
    if you find a way to get data on the target and but I tried to format the data target and stick with the installed MapaSource but put in the Target does not recognize and does not work, it only works with the program Unlocker IMG Fas 2.1 and the I said 2011.G32 files
    are 6 files in WinRAR to decompress that generate gmapsupp.img
    installs it automatically

    Now I understand. So this i s why you wanted to know how to make cure on the 82701000720 firmware. Very nice Ok, will leave it to you to make the "cure".

    1. After you install notepad++ download and extract this file into the folder Notepad++\plugin:

    [Only registered and activated users can see links. ]

    and you will have a very good Hex Editor for free in your Notepad++.

    2. If you still can't manage suggest this ones.
    [Only registered and activated users can see links. ]

    First suggest the PO to try the 500 cure version.

    3. Sorry, but I still couldn't understand was the nuvi formatted?
