So what you're saying is that the failure case is:

- Player is playing.
- Shut off car ignition.
- Player goes into standby mode because the ignition was shut off.
- Player continues to sit there in standby mode for X number of seconds.
- Player goes into full power off mode.
- Player stays in the dash.
- Turn on car ignition.
- Player boots.
- Player goes into standby mode after booting.

The desired and expected behavior is for the player to begin playing music at that last step instead of going into standby mode.

Yeah, I'd agree something's fishy there. It would be interesting to know if, when the failure case happens, if it's playing the music at the correct spot, or if it rolled back to the prior flash save.

Any chance the players exhibiting this behavior are in need of the diode fix?

Anyone know at exactly which point the player decides what its next bootbehavior is going to be, in the case of that series of events listed at the top of this message? And once it's made that decision, how/when that information is saved?

(The reason I ask is, what happens if it's at the step where it's sitting there for X number of seconds in standby mode after ignition shutoff, and, as Bitt suspects, the voltage drops below its threshold *at that moment*?)
