and have had no problems with it shutting down on ignition key off.
(I have the older 3300 model with the screen, so that has the advantage of readily confirming that it is off.)

But given that the Business CD has both ignition switched and non-switched power going to it,
something going wrong in the head unit could give rise to the intermittent Parrot shutoff problem you observe.

(I do get the occasional noisy startup of the Parrot that is often mentioned in user reviews, but that's a separate thing.)

Hard to say which is the culprit in your case, but at least you have a workaround.
