After 9.8 Upgrade GPS lost signal.

Hello everyone! Yesterday I upgraded my Garmin 735XT to 9.8 version and since than my GPS not worked. I tried some suggestions that I saw here, but nothing worked.  Some one knows how can I do downgrade to old version (9.4)? Maybe it work. 

  • Same problem! After upgrade to 9.8 no GPS anymore. And without GPS no correct time and date... Any solution?

  • Hi, I got solve the problem. First, delete the Garmin folder, you can do it when you plug the watch in the computer. Then restore defaults, start the watch but go to the open area with the sky clean, put the watch in some activity (run for exemple)  and wait for some minuts, observe the GPS sinal growing up, maybe around 10 minutes will get the sinal again. It worked to me.
