Smaller brands such as Navigon might present a problem, but those with Tom Tom, Garmin or Navman satnavs should be fine.
It is called Mio Transfer Hack C250 (don't worry about the 250 thing, C220 and C250 are identical devices in terms of functionality). So, before we put any map we like, we have to replace the "locked" files with some cracked ones. The license file basically "tells" the program which maps the owner is authorized to use. Get the files here: Extract the RAR archive you just downloaded somewhere on your hard disk. HARD REBOOT the device (press power button and keep it pressed until it switches off). If everything goes well, you'll see no difference.
Download it from here: is very simple to use, just plug the device, let the computer recognize it and then run the program. Generally, the pre-installed is designed in a way that user can only use the specific pre-installed map. Rename the original files located into the device's flash so if something goes wrong, you'll be able to go back instantly.

If you end up with a fucked up device, we also don't give a shit. Even if it doesn't start, connect it with your computer, insert the original DVD and select the option "Restore Original Mio Map Program Files". Go visit them and you'll find many many other splendid things about your device. This is simply because you don't actually need to do something like that, as maps / software updates offered from Mio use their own file exchange mechanism.
