    help SD Authentication

    Hello. I've read many posts and still can't find something that would help me get an updated map to work on my GPS. The GPS I have came with the car I bought, factory installed, in dash (it is a Honda Navigation unit, which has DVD, radio, GPS, USB).
    The Navigation software is Garmin, but it stores all of its map information, voices, vehicles, etc on an SD Card. (The SD Card contains the gmapbmap.img, gmapprom.img, Gmapprom.unl & gmaptz.img files in the Garmin folder, it also contzaind more files in that folder as well as several other folders like Fonts, Help, Voices, Vehicle, POI, etc) See attachment for a list of all files in the SD Card.
    Since I was trying to get an updated map but didn't want to mess up the SD card, I made a RAW copy of it into another SD Card, but when I put that copy into the unit, I get a cannot read map data, check SD card message. So I guess the map is locked to the SD Card.
    I then deleted the gmapprom.img & Gmapprom.unl files from the SD Copy and copied an UNLOCKED gmapprom.img file instead. When I put it into the unit I get a screen titled SD Authentication with an input box that reads "Please input the password." and I get a keyboard with the a-z & 0-9 keys. I'm able to enter up to 16 characters (The keyboard doesn't allow symbols nor spaces).
    How can I get that SD card password? I tried running the Hardware_IDExtractor tool on the copy SD, but it won't show anything under "Real Hard drive ID (hardware)". Although I don't think that would help much, as that would be the ID, not the password :/
    The facts are:
    - All the garmin information from the unit is stored in the factory SD Card
    - A RAW copy of it doesn't work, without modifyng its contents, I get a cannot read map data message
    - If I add an unlocked map to the RAW copy, naming it gmapsupp.img, I get a cannot read map data message
    - If I delete the gmapprom img & unl files from the raw copy and copy an unlocked map with filename gmapprom.img, I'm asked for the SD password.
    I would really appreciate any help; I've been reading full posts for the last couple of weeks and can't find a way to make the unit to accept a new SD Card & unlocked map.

    Thank you for your suggestion Catymag; so I just run JetMouse, enter the Navigation ID that comes in the "About" Screen of the GPS, hit the first generate button, and copy the "Software unlock code" into a new NotePad document (as is), which I would save as sw.unl in the Garmin folder of the copied SD card?
    Note: I would delete the original gmapprom img & unl files from the SD card and copy the new unlocked map as gmapprom.img

    Why RAW and not FAT32?
    Format it in FAT32 unlock map with gimgunlock and all be OK.
    Did you update your unit FW?
    When you copy SD conntent do you enable hidden sistem file and folder?
    Try to remove grmn0.gma from SD card.
    Please attach your PANA10SIG.PSI to post maybe here is stored your password.
    What is model number of your radio?

    And what about working of your device without gmapprom.img on SD?

    Hello spijun. The img file I'm copying is already unlocked, its called: Garmin Mexico NT 2013.20 Unlocked IMG, and it doesn't have any lock code when checking in GMapTool. Would it be unlocked differently using the tool you mention? Thanks for your help

    Hello Catymag. How can I get the SD Card ID? I tried using Hardware ID extractor, but the "Real hard drive ID (hardware)" field is blank. See attached screenshot.
    Is there another way in which I can get the SD card ID?
    Thank you, very much for your help.

    Hello Lolypop000. I tried using a raw copy tool (HDDRawCopy) after trying with a regular Fat 32 windows copy (w/hidden files), because I thought an exact clone might work, but neither of those copies work :/

    I don't think there's a FW update available as it is a 2012 Honda Navigation system that comes factory installed, or I don't know where I could get such FW update.

    I'll try removing the grmn0.gma file, as you suggest, and post results.

    The pana10sig.psi file contains the following two lines:

    PANA10SIGV1.00
    cmhd

    I don't know what the model of the radio is, I couldn't find a way to get that from the unit, sorry :/

    Thank you for your help, please let me know if you can think of anything else that I may try.
