I'm afraid electrically it doesn't; the system either has power or it doesn't!

Not necessarily, a bad connection can give fluctuations in voltage

Not when there's voltage regulators stepping down to consistent 5v and 3.3v rails.

If it were due to voltage drops from a bad connection your system would be power cycling, not touching itself up.

It seems the ghosts are gone but... my battery died, I assume from being loose, and then my NAV and RADIO button stopped working. Both functions will open from the menu screen So maybe there was an intermittent short somewhere that finally failed
