[time-nuts] Bricked Garmin GPS 18x LVC

[Jason Rabel]

That page you linked to says:

"I am reminded by Dave Hart that it was due to a firmware bug that bricks
the unit until it's left off power long enough to drain the capacitor that
retains its settings, sort of a poor-man's NVRAM.  This can take some
weeks."

Or I suppose if you are impatient you could open it up and de-solder the
super-cap if you don't want to wait weeks for it to drain on its own.
*Maybe* you will get lucky and that's all it will take?
