How to Unlock Navigon 2100 Release 4.2

This is my first unlocking guide for Navigon 2100. It is base upon the Mio C230 unlock release 4.1. What’s new is My Apps (WolfNCU) which lets you add your own programs to the desktop easily. A skins swticher is also included for you to switch skins for MN6.



Before you begin, make sure you read the post entirely and you have no questions about each step. A little background might help you understand what you are doing. At startup, Navigon executes autorunce.exe which invokes MN6, the navigation software for Navigon. We just change the name of the original autorunce.exe and put our unlocking script in its place. This way we trick the Navigon to run the unlocking script.

Step by Step Instructions

  1. Put the SD card that comes with Navigon into your computer’s card reader. If you don’t have a SD card reader, you can connect your Navigon to the computer directly using a mini-USB cable(not included).
  2. Change the file autorunce.exe on the SD card to autorunec.exe.
  3. Download the zip file from here. (This link has been updated to download the release 4.2.1)
  4. Unzip the file and copy everything to the SD card. Note that if you already have a Skins directory, just copy the content of Skins directory to your existing Skins directory. Here is a screenshot of the folders and files on the storage card’s root directory.
  5. Put the SD card back to the unit. Turn it off completely by pressing and holding the power button for a few seconds.
  6. Turn on Navigon 2100 by pressing the power button and holding it for a few seconds. A dialog pops up telling you the unlock is done and begging for donation. πŸ™‚ Click on OK to continue.

Mini Manual

There are 3 desktops included in this package. You can use the left and right arrows on the lower right corner to switch between the desktops. The top row and bottom row are the same for each desktop. The top row from left to right:

  • Restart: Restarts the unit.
  • Toggle Screen Orientation: Toggles the screen between landscape or portrait mode.
  • Taskbar: Brings up the taskbar.
  • Toggle Keyboard: Toggles MioTool(keyb.exe) which you can use to open an on-screen keyboard. You need a stylus to us it. Make sure the cursor is in the input field of the window when you use it. Tap the ab icon again to close the on-screen keyboard.

The bottom row from left to right:

  • GPS: Invokes MN6.
  • Media: Invokes TCPMP. This is a versatile media player. It plays various video formats and MP3. It can also be used to view photos. I added the plugin to play FLV video downloaded from YouTube or other flash video sites. Plugins for playing Podcast video are also included.

  • XnViewPocket: Image viewing application. You can use it for photo slide show.
  • My Apps: If you want to add your own programs, this is the place.

Games Desktop

In this desktop, there are a lot of new games. Most of the games are from XFlib. If you like the games, please consider a donation to their site. You can download a lot more games from the site. Some games run in portrait mode. Ameridan has come up with a way using scripts to rotate the screen automatically. I have borrowed the scripts to run these games.

  • Lights On: Invokes LightsON. The goal of the game is to turn all lights on.
  • Free Cell: Invokes FreeCell, a poker game.
  • Sudoku: A Sudoku game from XFlib.
  • Caisses: A Sukoban clone game from XFlib.
  • HexaVirus: My personal favorite from XFlib. Your goal is to active every virus in 30 moves or less.
  • Aquella: A JezzBall-like game from XFlib.
  • BallBreaker: An interesting game from XFlib to test your reflexes. All the balls are shooting at your cursor. Try to lure the balls to hit the block(s) and break them.
  • SmartMahjongg: My favorite PocketPC game. It’s now possible now that we have .Net compact framework 3.5. The game is a bit slow to load, please be patient. If you like it, please consider a donation. This is the author’s site.
  • Tetris: A classic Tetris game. Click on the block to rotate it. Click on the left or right side of the window to move the block.
  • Shift: Another game from XFlib. Click on the border of the screen to move the blocks that can move in the direction. When 3 or more of the same block form, they disappear.

  • Snapshot: Invokes CapScrUtil. A screen capture utility. Remember to store the image to either Storage Card or My Flash Disk for easy access to the screenshots.

  1. I have not found a way to terminate MN6 gracefully. Therefore, a utility called WolfToolbar is included for quiting MN6. WolfToolbar is executed first every time you try to start MN6. You can exit out MN6 by clicking on WolfToolbar icon and then click on Task. This brings up the task manager, you then click on Process tab and select MN6.exe to terminate it. If you think WolfToolbar is really annoying and you don’t want to use it, find the file MioNav.mscr in the Script directory and delete the line that says
    Run ("\Storage Card\Script\wolftoolbar.exe")
  2. If you want to use your own background image, just create a 320×240 bitmap file. Put them in the Scriptdesktop directory. Edit the ini files in the directory to use the bitmap file you created. main.ini is for Main desktop, gmaes.ini is for Games desktop and utilities.ini is for Utilities desktop. Change the variable BackgroudBitmap to point to the new file.
  3. If you want to change or add the icons(shortcuts) on the desktop, you can do so by editing the files in note #2. An icon entry is like this.
    x = 0
    y = 95
    Command = \Storage Card\Script\your_program.exe
    SizeNormal =64
    SizePushed =64
    ScaleAlpha = 80
    IconNormal = icons\youricon.ico
    ScaleAlpha = 100
    IconPushed = icons\youricon.ico
  4. When you have the program and icon(64×64) ready, copy the program to Script directory and copy the icon to Scriptdesktopicons directory and modify the variable Command, IconNormal and IconPushed. Note that you have to use absolute path for Command, but use relative path for IconNormal and IconPushed. If you follow this rule, you can use the included SystemInformation32.exe in that directory to test the desktops on your computer. This tool is very useful for those who like to change the desktops frequently. I have commented out some of the ICONXPBUTTON sections on the ini files. If you want to use them, remove the # signs in front of the lines.
  5. If you experience programs with your unit, you can hard reset the machine using the power button on the top.
  6. The use of unlicensed maps is illegal. Please don’t ask me where can you get maps not licensed for your device or how can you get MN6 to recognize the unlicensed maps. Any question regarding unlicensed maps will either be deleted or ignored.

Backing Off

If you don’t like it the way it is, you want to undo everything. It’s very easy to revert back to the factory state, just delete all the files you copied to your unit and rename the autorunec.exe back to autorunce.exe. Hard reset your unit afterward.

  1. i did the hack now i cant set it back to the factory setup can someone help i turn on the unit and stays in the splash window of navigon thats it navigon 2100 i did the reset

    • If you delete all the files you copied to the SD card and rename the autorunec.exe back to autorunce.exe. Hard reset the GPS and your unit will be back to the factory setup.

  2. First, I apologized to the knowledge of English. I use google translator.

    Please send me someone to backup registry navigon 2410th Specifically I need hlmk / loader

    Trying to remove miopocket 3.0 with my flash drive I’ve wiped the registry and now I’m in trouble. The device responds, but I do not have pictures. White screen: (

    • I do not have the registry key to send you. However, if you hard reset your Navigon 2410, you might be able to get the registry back.

  3. Hi,

    I am trying to get your bundle working on my new Navigon 8450 with some success, however I’m not quite there yet. I think that the 8450 comes with a pretty bare-bones version of windows CE; for example, there is no taskbar. The utility included to show it fails with an error about not being able to find the window.

    About half the apps run, and the other half cause the device to reboot when I start them. A stab in the dark – perhaps missing or incompatible DLLs?

    I’m happy to put some work in getting this going if you could point me in the right direction; you must have faced all this sort of stuff when creating the bundle to begin with πŸ™‚

    – Phil

    • You can download a useful application to find out what are the missing DLLs for a certain application.

      Once you know what are missing, you can just search for the files. There are quite a few unlock packages out there. You might find them useful.

  4. Can someone plz help me? I added this to my 2100max and the gps did not work. so I deleted the files and it will not load up past the start screen πŸ™ I even downloaded the factory files and still nothing. anyone please help me? Thanks!

    • I am sorry to hear that. What’s the message when you tried to use the factory files to restore your SD card? You might have to hard reset the GPS after restoration.

      • there is no message. just the navigon background, and thats it. wont load up or anything. and how do I hard reset? just press the reset button on the bottom? if so I already did that πŸ™


        • Yes, that’s the reset button. You can try to find other 2100 max user and see if they can share the files on the SD card with you. Otherwise, you might have to contact Navigon support and ask them how can you restore the files on the SD card.

          • I did download the factory files off pirate bay. has everything on em, but it still does the same. Is there somthing else I have to do? like edit something? And I cant contact them cause I bought it off craigslist and I have no paperwork for it.

          • I don』t think you need proof of purchase to register your unit with Navigon. Why don』t you give it a try.

            If you have everything on the SD card and you have reset the unit. The only thing you can try is to use a different SD card.

            It’s also possible that your unit is broken. These GPS units are not made to last. My old C230 is broken as well.

  5. I’m getting the exact same problem that Ed received. I first of all tried the unlock. The GPS wouldn’t respond, tried to come back to factory conditions.. downloaded the factory files from piratebay just as Ed did. Loaded them back to the SD card.. plugged it in and even though the files are not there.. and the SD card is formatted it shows “wolftoolbar.exe” on the screen as soon as i turn the unit on. Then, it goes to the navigon screen and freezes.

    Any thoughts?

  6. I have this working just fine on my Navigon 2100. I was wondering if you know of a way to get iGo8 on it and/or how to get map updates.

    Navigon no longer supports map updates in the USA (i think).

    Please send me an e-mail if you can possibly help.

  7. please i whant to restore my device an i am missing all the files. my navigon did not come with the sd card i need all the files for the sd card and the dvice
