Hi I am new member. My TTGo700 stopped navigating for a while and I asked help from TT customer service. They send me back replaced/ refurbished TTGo700. It works. But it comes with old western Europe map. I bought map V7.02 and used it on my old TT. I contacted Customer care and send them prove of my purchase of map. Customer care send me e-mail to download V7.02 on refurbished TT. I followed his advice, back up- format-paste- everything looked good. I disconnected device to see new map on it. TT showed no map found and it stuck there. I contacted customer care 24 hours ago and no reply yet. Can anyone help me out. Thanks for your time.
