the electronic noises are from the NAV/DVD spinning...

even when the vehicle is off... there's still a bit of activity going on...

i believe the entire vehicle shuts down 5-10 minutes after ignition cutoff..

but, for whatever reason, the NAV/DVD spins from time to time..

noticed this while sitting in the car for a long period of time while waiting for the wife to come out of a dept store...
