I also have Go 710.
I honestly tried to find the navcore for it. All I got was some links that lead nowhere and captcha that was not captcha. I am really sick and tired of the games that those download sites play. I think they are doing great work against themselves. I am getting to the point of just buying a new device with all the nnew games new new maps rather than play their games.
Please help me stay on the dark side.
