Have a Tesla Model S.
Went away on a trip for a week and had it plugged in the whole time -- when I returned home:
(A) the car started requesting my "Starting Address" or something similar to that.
(B) The Navigation bookmarks were wiped out.
(C) The GPS seems to have failed and the car was "stuck" at my home location.
Everything else seems to be working fine and all other settings seem to have stayed.
I hunted on forums and found someone mention to reboot the car (power down, don't touch anything, wait 3+ minutes) -- tried that many times and nothing.
Also tried rebooting the two consoles using the buttons on the steering wheel.
So frustrating... Any thoughts?
