@jojobastos here, try this SD unlock, based on the files (device.xml) from a backup provided by apolyps3. It's all in the package, just extract and copy all folders to a empty fat32 formatted SD card. Power of/on your device and you should see new menu with icons. You can run Primo from the corresponding icon. It's already configured to work on your mio you just need to add maps. You don't even need to copy anything to your Mio, not even a backup files provided above..
Spoiler: link
good luck!
