Haven't so far @Home have had it running short time on faux DC still haven't had any 'stuck jiffies'. I think it may have to do w/actually being in the car enviroment (power off/on/low/high) that might start it from when it happened to me. I do recall that when I started the car the error was there and nothing else but music was still playing, when I pulled the unit out It made my speakers pop, which I have had before w/o the error just shutting off ignition.
