I received my new Fenix 5 yesterday (12/17), with software v7.00. With me standing outside my home, in the open, it was able to quickly acquire GPS signals. Today, I installed the v7.10 software, and the F5 does not get GPS, in the same location as yesterday; I have waited as much as 10 minutes before giving up on it. Seems to be a problem with v7.10.
