1. Turn on C230 and connect it to the computer using a USB cable(not included in the package).
2. C230 is shown 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.
3. Rename the folder F:\MioMap\MioMap to F:\MioMap\MioMap2
4. Download MioC230r1.zip from http://www.mediafire.com/?fczmng1ixpy
5. Extract MioC230r1.zip and find the two folders MioMap and Script
6. Copy MioMap to F:\MioMap\ and copy Script to F:\ . The directory structure is like the screenshot.


7. Disconnect Mio C230. The device soft reset automatically and runs the file manager.
8. Use the file manager and browse to \My Flash Disk\MioMap\MioMap . You might need to use a stylus to do it.
9. Tap AUTOPATCHER.exe twice to run the script.
10. C230 soft reset again

If you hard reset the machine, the changes are gone. However, the hacked version of MioMap directory is still there. It would run the file manager again. Just follow the steps 8 and 9 to run the AUTOPATCHER.exe and you are good

What is the purpose of unlocking the MIO C230? I just purchased one and want to know what additional things I can fo with it.
