Mio C320 unlock and update

Small Review

Mio C320 is a mid-range device launched a few years ago. A big and bright screen, a stable processor and reliability have ensured the success of this satnav. Unfortunately updating maps and software stopped   in 2008, and the Mio C320 has been replaced with newer models from Mood and Spirit range.


Mio C320 update or unlock

Unfortunately, Mio C320 received its last map and software update in 2008, so the maps in this device are by now outdated and could cause as problems.

If the official update is not possible for Mio C320, then we could unlock this Mio device and install other navigation software or some utilities (like a media player).

This device can be easily unlocked and then run a new 2013 software and maps like iGO8 or Mireo –which is similar to MioMap 2008.
