lhtai said:You can find hacking information and a lot more in this previous post. As for other software I have seen iGo 8 and Garmin XT working on this Mio C320. I am not sure how to get Garmin XT to work but GPSpassion.com forum may has some info. Or ask Google!
Yes, this link (from Staples deal) is rich in information for hacking the Mio C320. Please add your questions about hacking there AFTER you have read everything that's already posted there. Actually, if you really do read everything there, you shouldn't even need to ask anything 
Other websites with info include GPS Passion, GPS Underground, Mio Passion, and Mio Heaven (must see, single page). The last link is perfect for you if you don't care to turn the Mio into a Pocket PC or change to TomTom, Garmin, etc., but just want to install text-to-speech (read street names aloud) and/or update maps.
