Mio C220 / C250 Unlock

In short:

• Place Mio C220 / C250 Pseudo Unlock (4.3MB) on a SD Card.
• Insert the Card while the device is running. A file-manager will start.
• Backup your "MioMap" Folder which is inside "\My Flash Drive\".
• Delete the folder "MioMap" inside "\My Flash Drive\".
• Run "Setup.exe" on the SD Card.
• Starting MioMap from the Main Menu will now open a menu that allows you to start some apps. You can add more, if you want.

Done!
