Fenix 5 Plus Maps/Navigation Issues

I recently bought a Fenix 5 Plus and have been having a lot of issues with the maps and navigation. The majority of the time I try to use either, the watch ends up freezing and resetting. I have updated the firmware and all maps and have done soft and hard resets. I ended up returning the watch and getting another one and I am having the same problem, which may suggest user error. Any suggestions? Both devices arrived with zero battery with seemed odd to me (I though most electronic devices shipped with 30-70% battery). Any help would be appreciated, thanks!
