How to Unlock a Mio C320by Ben David
The Mio C320 is a 4.3-inch widescreen automobile GPS navigation system. The device features turn-by-turn voice and visual guidance as well as a 20-channel SIRFstarIII GPS receiver. It also has a lightweight portable design and preloaded maps. Some people might be interested in unlocking this GPS device to add maps that are not included with its preloaded set.
Connect the Mio C320 to your computer via USB port connection.
Browse the internal Flash memory file via Windows Explorer. Windows Explorer will automatically map the flash memory files of the device when it is connected to the computer.
Download the cracked files (see Resources) you need to replace in the device's flash memory to unlock it.
Find and replace the following files in the flash memory: miomap.exe, miomap.exe.id, license.db and data.zip. These files are the "locked" files that need to be replaced. Once they are replaced with the cracked ones, the device will be unlocked.
