I tested the route management from this thread and found it quite useful. I have decided to publish this interim release. This release has many more files. If you have not moved some of your map files to the storage card. This is the first thing you will have to do. This release uses about 9 MB of space. The stock Mio C230 has about 5 MB of free space, that means we need about 4 MB more. Please see this post to move some map files to the storage card before you begin.
Here are what’s new about this release.
- Route management.
- New game ICBM.
- DATA.ZIP now includes EASY route option.
BEFORE YOU FOLLOW THE PROCEDURES TO MODIFY YOUR MIO C230. YOU KNOW THAT YOU MIGHT RENDER YOUR C230 UNUSABLE AND YOU MIGHT VOID YOUR WARRANTY. YOU DO THIS AT YOUR OWN RISKS. THE FOLLOWING STEPS HAVE BEEN TESTED ON US MODEL OF MIO C230 ONLY. THEY ARE NOT MEANT FOR MIO C230 PURCHASED IN OTHER COUNTRIES.
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. By default, Mio C230 executes MioMap.exe in the MioMapMioMap folder on the internal flash disk when starts up. We want to rename the original MioMapMioMap to MioMapMioMap2 and put the unlocking scripts in its place. This way, we trick the unit to run the unlocking scripts. The zip file you are going to download includes 2 folders (MioMap, Script) and 1 zip file (DATA.ZIP). MioMap folder contains the unlocking scripts, it goes to MioMap directory on the internal flash disk. After copying, its path is MioMapMioMap. Script folder contains applications and other support files, it goes to root directory of the internal flash disk. DATA.ZIP adds the Exit Door to MioMap, so that you can exit out MioMap without other application or hard resetting your unit. Other changes are included in DATA.ZIP file (Export track log button and EASY route option). It has been reported that the DATA.ZIP file is not compatible with EU model. You’ll need to modify your original DATA.ZIP by following this post.
Step by Step Instructions
- Turn on C230 and connect it to the computer using a USB cable(not included in the package).
- The internal flash disk shows up as a flash drive called Mio Device. Mine is assigned as F drive. I’ll use F drive in the following steps. Substitute it with the actual drive letter of your system.
- Rename the folder F:MioMapMioMap to F:MioMapMioMap2 .
- Download MioC230r3.1.zip from this site .
- Extract MioC230r3.1.zip and find the two folders MioMap, Script and a file DATA.ZIP. (DO NOT UNZIP DATA.ZIP)
- Copy MioMap to F:MioMap and copy Script to F: . After you are done, there are two folders (MioMap and Script) under Mio Device. There are two folders (MioMap and MioMap2) under the first level MioMap. This is the screenshot of the directory structure. The downloaded folders are in red rectangle.
- Make a backup copy of your DATA.ZIP in F:MioMapMioMap2 and replace it with the DATA.ZIP in step 5. If you want to keep your own DATA.ZIP or if you have an EU model, please see this post to modify it by yourself.
- Disconnect Mio C230. The device soft reset automatically. If for some reason, the device didn’t soft reset. Use the switch on the back to do a hard reset.
- You are presented with this screen. Tap the right unlock icon to run the script to unlock the unit or tap the left GPS icon to run MioMap directly. If you decide to run MioMap directly, you can exit MioMap from the main screen to get back to this screen.
- C230 soft resets again. Here is the screenshot of the device after unlocking.
After unlocking, notice there is a small icon “ab” in the top left corner. If you tap on it, it opens up 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 it again to close the on-screen keyboard.
Here is the brief description of each icon:
- Paint: Invokes JZPaint16, a paint program for creating bmp files. Note that whenever you save a file, it takes a long time and the screen freezes during the process. Just wait a few moments.
- Calculator: Invokes MyCalculator. To exit out MyCalculator, tap About and then the “X” in the about screen.
- Lights On*: Invokes LightsON. The goal of the game is to turn all lights on.
- Free Cell*: Invokes FreeCell, a poker game. When the game runs, it only covers part of the screen.
- ICBM*: The classic Missile Command clone game.ã€€* – Some readers have reported problems running these games. If you have same problems, please don’t use them.
- Restart: Soft resets the device. You might want to restart your machine whenever some applications crash or the desktop is in a strange state.
- Resinfo: Invokes Resinfo. It shows you some resources informations for your device. Kinda like task manager in Windows. You can use it to terminate applications or processes.
- 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.
- Routes: Route Management. See the Note section for instruction.
- Settings: Invokes MioUtility, a control panel like application for adjusting backlight, volume, screen, power, date/time and language.
- GPS: This runs MioMap.
- 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.
- Explorer: Invokes FileMan CE, a file manager for CE devices. You can use it to launch other programs not on the desktop.
- Photos: Invokes GQe. You can use it to view photos on the storage card.
- Notes: Invokes PocketNotePad, a notepad program for creating/viewing text files.
- If you want to use your own background image, just create a 320×240 bitmap file. Name it back.bmp and put it in the F:Script folder. I have also included a clown fish background image in that folder. To use it, just rename the original back.bmp and rename the F:Scriptback-clownfish.bmp to F:Scriptback.bmp .
- If you want to change the icons(shortcuts) on the desktop, you can do so by editing the file F:Scriptmain.ini .
- You will need to hard reset Mio C230 every time you disconnect the unit from the computer.
- If for whatever reason, you cannot exit a certain application, you can use Resinfo to terminate the application. Tap the “ab” icon on the upper left corner. Tap “Ctl” and then “Esc” on the on-screen keyboard, this brings up taskbar. Once taskbar appears, tap “Programs” and then “Resinfo”. Use “Tasks” tab of Resinfo to terminate the application (task). You might want to soft reset (restart) the unit.
- Route management lets you Save/Load/Delete/Rename routes. The default location for routes is at F:Routes. If you have saved your routes in other location, you can move them to here. To save a route, start MioMap. Plan a route as you wish. You might want to disable off-route automatic recalculation(Home -> Settings -> General -> Off-route recalculation) when you plan a route. When you are done planning, exit MioMap. Then click on Routes icon to run the route management program and click on “Save current Route” to save it. To load a route, click on Routes icon. Then click on “Load a saved Route”. Pick the route you want and click on OK. The MioMap starts up automatically with the route your picked. The other functions are pretty self-explanatory.
If you don’t like it the way it is, you want to undo everything. Here are the steps.
- Turn on C230 and connect it to the computer using a USB cable.
- Rename the folder F:MioMapMioMap to F:MioMapMioMap3 and rename the folder F:MioMapMioMap2 to F:MioMapMioMap .
- Restore your original DATA.ZIP to the F:MioMapMioMap .
- Disconnect the cable and hard reset C230 using the switch on the back.
If your Mio C230 is not working at all even after you perform the aforementioned steps, you can use the DVD that came with your unit to restore it.

I published the original unlock guide on 10/31/2007. The guide is a FIRST and ORIGINAL unlocking guide for Mio C230. The guide has made hacking/unlocking Mio C230 possible and it has inspired other efforts for making Mio C230 a wonderful device to own.
