Awesome. So I woke the other day and my F5X got automatically updated to 7.6. Maps are gone. Upon boot it says Cannot authenticate maps, contact map vendor for help. Good. Only the basemap is visible.
So I tried the following:
1) Soft reset
2) Reinstall FW
3) Reinstall maps via Express.
4) Delete maps from watch and reinstall them from scratch.
Today I took the plunge and did the hard reset. And guess what. even THAT did not help.
Of course I tried the suggested and contacted G support. It is, indeed, a fortress of ignorance and was of zero help whatsoever.
I do not have any weird maps on the device, just the factory set.
Ideas?
