I updated my 760 a couple of weeks ago and all went well. Till last week when I turned the unit on and noticed all the mapping had gone and the screen just showed the basic map pages with no routing. Very annoying as we were in the middle of France. I tried resets but nothing worked. Luckily, I had another sat nav with me and used that. \nI reloaded the maps when we got home and it seems to be working ok\nI had a similar problem with my Nuvicam after the last but one update. All the terrain colouring and 3D shading has gone. Garmins solution is to sell me another as it’s out of warranty, even though their software update screwed it up! \nThe latest updates have not improved the display though.
